This patch adds multi-TC support.
PTP is automatically disabled when the user enables more than 2 TCs,
otherwise traffic on TC2 won't quite work, because it's reserved for PTP.

This patch contains the following changes:
* add cfg->is_ptp (used for PTP enable/disable switch, which
is described in more details below);
* add cfg->tc_mode (A1 supports 2 HW modes only);
* setup queue to TC mapping based on TC mode on A2;
* remove hw_tx_tc_mode_get / hw_rx_tc_mode_get hw_ops.
In the first generation of our hardware (A1), a whole traffic class is
consumed for PTP handling in FW (FW uses it to send the ptp data and to
send back timestamps).
The 'is_ptp' flag introduced in this patch will be used in to automatically
disable PTP when a conflicting configuration is detected, e.g. when
multiple TCs are enabled.

100GbE Intel Wired LAN Driver Updates 2020-05-21
This series contains updates to ice driver only. Several of the changes
are fixes, which could be backported to stable, of which, only one was
marked for stable because of the memory leak potential.
Jake exposes the information in the flash memory used for link
management, which is called the netlist module.
Henry and Tony add support for tunnel offloads.
Brett adds promiscuous support in VF's which is based on VF trust and
the new vf-true-promisc flag.
Avinash fixes an issue where a transmit timeout for a queue that belongs
to a PFC enabled TC is not a true transmit timeout, but because the PFC
is in action.
Dave fixes the check for contiguous TCs to allow for various UP2TC
mapping configurations. Also fixed an issue when changing the pause
parameters would could multiple link drop/down's in succession, which in
turn caused the firmware to not generate a link interrupt for the driver
to respond to.
Anirudh (Ani) fixed a potential race condition in probe/open due to a
bit being cleared too early.
Lihong updates an error message to make it more meaningful instead of
just printing out the numerical value of the status/error code. Also
fixed an incorrect return value if deleting a filter does not find a
match to delete or when adding a filter that already exists.
Karol fixes casting issues and precision loss in the driver.
Jesse make the sign usage more consistent in the driver by making sure
all instances of vf_id are unsigned, since it can never be negative.
Eric fixes a potential memory leak in ice_add_prof_id_vsig() where was
not cleaning up resources properly when an error occurs.
Michal to help organize the filtering code in the driver, refactor the
code into a separate file and add functions to prepare the filter
information.
Bruce cleaned up a conditional statement that always resulted in true
and provided a comment to make it more obvious. Also cleaned up
redundant code checks.
Tony helps with potential namespace issues by renaming a 'ice' specific
function with the driver name prepended.

Support for fdb ECMP nexthop groups
This series introduces ecmp nexthops and nexthop groups
for mac fdb entries. In subsequent patches this is used
by the vxlan driver fdb entries. The use case is
E-VPN multihoming [1,2,3] which requires bridged vxlan traffic
to be load balanced to remote switches (vteps) belonging to
the same multi-homed ethernet segment (This is analogous to
a multi-homed LAG but over vxlan).
Changes include new nexthop flag NHA_FDB for nexthops
referenced by fdb entries. These nexthops only have ip.
The patches make sure that routes dont reference such nexthops.
example:
$ip nexthop add id 12 via 172.16.1.2 fdb
$ip nexthop add id 13 via 172.16.1.3 fdb
$ip nexthop add id 102 group 12/13 fdb

Todays vxlan mac fdb entries can point to multiple remote
ips (rdsts) with the sole purpose of replicating
broadcast-multicast and unknown unicast packets to those remote ips.
E-VPN multihoming [1,2,3] requires bridged vxlan traffic to be
load balanced to remote switches (vteps) belonging to the
same multi-homed ethernet segment (E-VPN multihoming is analogous
to multi-homed LAG implementations, but with the inter-switch
peerlink replaced with a vxlan tunnel). In other words it needs
support for mac ecmp. Furthermore, for faster convergence, E-VPN
multihoming needs the ability to update fdb ecmp nexthops independent
of the fdb entries.
New route nexthop API is perfect for this usecase.
This patch extends the vxlan fdb code to take a nexthop id
pointing to an ecmp nexthop group.
Changes include:
- New NDA_NH_ID attribute for fdbs
- Use the newly added fdb nexthop groups
- makes vxlan rdsts and nexthop handling code mutually
exclusive
- since this is a new use-case and the requirement is for ecmp
nexthop groups, the fdb add and update path checks that the
nexthop is really an ecmp nexthop group. This check can be relaxed
in the future, if we want to introduce replication fdb nexthop groups
and allow its use in lieu of current rdst lists.
- fdb update requests with nexthop id's only allowed for existing
fdb's that have nexthop id's
- learning will not override an existing fdb entry with nexthop
group
- I have wrapped the switchdev offload code around the presence of
rdst

This series contains updates to igc and e1000.
Andre cleans up code that was left over from the igb driver that handled
MAC address filters based on the source address, which is not currently
supported. Simplifies the MAC address filtering code and prepare the
igc driver for future source address support. Updated the MAC address
filter internal APIs to support filters based on source address. Added
support for Network Flow Classification (NFC) rules based on source MAC
address. Cleaned up the 'cookie' field which is not used anywhere in
the code and cleaned up a wrapper function that was not needed.
Simplified the filtering code for readability and aligned the ethtool
functions, so that function names were consistent.
Alex provides a fix for e1000 to resolve a deadlock issue when NAPI is
being disabled.
Sasha does additional cleanup of the igc driver of dead code that is not
used or needed.

Change min() macros to min_t() which has compare type specified and it
helps avoid precision loss.
In some cases there was precision loss during calls or assignments.

some cases where a simple cast was needed.
Callers were were passing data that is a u16 to

As soon as the driver registers the PF netdev, userspace utilities
like NetworkManager try to bring up the associated interface. When
this happens, the driver may not have finished initializing fully,
resulting in a bunch of errors in the interface up flow.
The driver already has a mechanism to indicate if it's not up yet;
by setting the __ICE_DOWN bit in pf->state, but this bit gets
cleared too early in the current flow. So clear this bit only when
the driver is fully up. Also check for the same bit in the ice_open
flow, and return -EBUSY if the bit is set.
Also in ice_open, replace references of vsi->back with a local
variable.

Currently, the ice driver is setting a PHY configuration,
which causes a link drop, and then additionally it calls
for a nway_reset, which restarts auto-negotiation on the
link, which also causes a link drop. These two link
events in such close timing is causing the FW to not be
able to generate a link interrupt for the driver to
respond to.
Remove the unnecessary auto-negotiation restart from the
set pauseparams flow. Also remove error path that
would have performed an ice_down/ice_up as that is
also unnecessary.

When there's a Tx timeout for a queue which belongs to a PFC enabled TC,
then it's not because the queue is hung but because PFC is in action.
In PFC, peer sends a pause frame for a specified period of time when its
buffer threshold is exceeded (due to congestion). Netdev on the other
hand checks if ACK is received within a specified time for a TX packet, if
not, it'll invoke the tx_timeout routine.

Implement promiscuous support for VF VSIs. Behaviour of promiscuous support
is based on VF trust as well as the, introduced, vf-true-promisc flag.
A trusted VF with vf-true-promisc disabled will be the default VSI, which
means that all traffic without a matching destination MAC address in the
device's internal switch will be forwarded to this VF VSI.
A trusted VF with vf-true-promisc enabled will go into "true promiscuous
mode". This amounts to the VF receiving all ingress and egress traffic
that hits the device's internal switch.
An untrusted VF will only receive traffic destined for that VF.
The vf-true-promisc-support flag cannot be toggled while any VF is in
promiscuous mode. This flag should be set prior to loading the iavf driver
or spawning VF(s).

rule() and igc_ethtool_add_nfc_rule(), which are called by .get_rxnfc
and .set_rxnfc ethtool ops, since ethtool subsystem is the one who deals
with them in big endian order.

The Network Flow Classification (NFC) support code from IGC driver uses
terms such as 'rule', 'filter', 'entry', 'input' interchangeably when
referring to NFC rules, making it harder to follow the code. This patch
renames IGC's internal APIs, structs, and variables so we stick with the
term 'rule' since this is the term used in ethtool APIs. It also removes
some not applicable comments along the way. No functionality is changed
by this patch.

This patch adds the prefix 'igc_ethtool_' to all functions defined in
igc_ethtool.c so they align with the name convention already followed by
other parts of the driver (e.g. igc_tsn, igc_ptp). Also, this avoids
some name clashing with functions added to igc_main.c by upcoming
patches in this series. No functionality is changed by this patch, just
function renaming.

The local function igc_max_channels() is a pointless wrapper around
igc_get_max_rss_queues(). This patch removes it and updates the callers
accordingly. It also does some cleanup on igc_get_max_rss_queues().

We are seeing a deadlock in e1000 down when NAPI is being disabled. Looking
over the kernel function trace of the system it appears that the interface
is being closed and then a reset is hitting which deadlocks the interface
as the NAPI interface is already disabled.
To prevent this from happening I am disabling the reset task when
__E1000_DOWN is already set. In addition code has been added so that we set
the __E1000_DOWN while holding the __E1000_RESET flag in e1000_close in
order to guarantee that the reset task will not run after we have started
the close call.

This patch adds support for Network Flow Classification (NFC) rules
based on source MAC address. Note that the controller doesn't support
rules with both source and destination addresses set, so this special
case is checked in igc_add_ethtool_nfc_entry().

This patch extends MAC address filter internal APIs igc_add_mac_filter()
and igc_del_mac_filter(), as well as local helpers, to support filters
based on source address.
A new parameters 'type' is added to the APIs to indicate if the filter
type is source or destination. In case it is source type, the RAH
register is configured accordingly in igc_set_mac_filter_hw().

In igc_adapter we keep a sort of shadow copy of RAL and RAH registers.
There is not much benefit in keeping it, at the cost of maintainability,
since adding/removing MAC address filters is not hot path, and we
already keep filters information in adapter->nfc_filter_list for cleanup
and restoration purposes.
So in order to simplify the MAC address filtering code and prepare it
for source address support, this patch removes the mac_table from
igc_adapter.
