We already have a workaround for a couple of switches whose internal
PHYs only have the Marvel OUI, but no model number. We detect such
PHYs and give them the 6390 ID as the model number. However the
mv88e6161 has two SERDES interfaces in the same address range as its
internal PHYs. These suffer from the same problem, the Marvell OUI,
but no model number. As a result, these SERDES interfaces were getting
the same PHY ID as the mv88e6390, even though they are not PHYs, and
the Marvell PHY driver was trying to drive them.
Add a special case to stop this from happen.

Jeff Kirsher says:
====================
100GbE Intel Wired LAN Driver Updates 2018-11-13
This series contains updates to the ice driver only.
Brett cleans up debug print messages by removing useless or duplicate
messages, and make sure we assign the hardware head pointer to head
instead of the software head pointer. Resolved an issue when disabling
SRIOV we were trying to stop queues multiple times, so make sure we
disable SRIOV before stopping transmit and receive queues for VF.
Tony fixes a potential NULL pointer dereference during a VF reset.
Anirudh resolves an issue where we were releasing the VSI before
removing the VSI scheduler node, which was resulting in an error "Failed
to set LAN Tx queue context, error: -1". Also fixed the guaranteed
number of VSIs available and used by discovering the device
capabilities to determine the 'guar_num_vsi' per function, rather than
always using the theoretical max number of VSIs every time.
Dave avoids a deadlock by nesting RTNL locking, so added a boolean to
determine if the RTNL lock is already held.
Lev fixes bad mask values which would break compilation.
Piotr increases the receive queue disable timeout since it can take
additional time to finish all pending queue requests.
Usha resolves an issue of VLAN priority tagged traffic not appearing on
all traffic classes, which was causing ETS bandwidth shaping to not work
as expected.
Henry fixes the reset path to cleanup the old scheduler tree before
rebuilding it.
Md Fahad removes a unnecessary check which was causing a driver load
error on platforms with more than 128 cores.

The "FE bit" in the description means the last description for
a packets. When HW GRO enable, HW write data to ring every
packet/buffer, there is greater probability that driver handle
with the describtion but HW still not set the "FE bit".
When drier handle the packet and HW still not set "FE bit",
driver stores skb and bd_num in rx ring, and continue to use the
skb and bd_num in next napi.

Move IRQ configuration for IP101A/G from config_init to config_intr
callback. Reasons:
1. This allows phylib to disable interrupts if needed.
2. Icplus was the only driver supporting interrupts w/o defining a
config_intr callback. Now we can add a phylib plausibility check
disabling interrupt mode if one of the two irq-related callbacks
isn't defined.
I don't own hardware with this PHY, and the change is based on the
datasheet for IP101A LF (which is supposed to be register-compatible
with IP101A/G). Change is compile-tested only.

In preparation of handling more Qdisc types switch to a different
offload strategy. We have now recreated the Qdisc hierarchy in
the driver. Every time the hierarchy changes parse it, and update
the configuration of the HW accordingly.
While at it drop the support of pretending that we can instantiate
a single queue on a multi-queue device in HW/FW. MQ is now required,
and each queue will have its own instance of RED.

RED qdisc will replace its child Qdisc with a new FIFO queue if
it is reconfigured and the limit parameter is not 0.
This means that when it's created with limit of 0 it will have no FIFO,
and all packets will be dropped. If it's changed and limit is specified
it will loose its existing child (implicit graft). Make sure we mark
RED Qdisc child as NFP_QDISC_UNTRACKED if its not the expected FIFO.
nfp_abm_qdisc_replace() will return 1 if Qdisc already existed.

Using graft notifications recreate in the driver the full Qdisc
hierarchy. Keep track of how many times each Qdisc is attached
to the hierarchy to make sure we don't offload Qdiscs which are
attached multiple times (device queues can't be shared). For
graft events of Qdiscs we don't know exist make the child as
invalid/untracked.
Note that MQ Qdisc doesn't send destruction events reliably when
device is dismantled, so we need to manually clean out the
children otherwise we'd think Qdiscs which are still in use
are getting freed.

L2 EtherType filters allows to filter packet by EtherType field or
both EtherType and User Priority (PCP) field of 802.1Q.
UserPriority (vlan) parameter must be accompanied by mask 0x1FFF. That
is to distinguish VLAN filter from L2 Ethertype filter with
UserPriority since both User Priority and VLAN ID are passed in the
same 'vlan' parameter.
Example:
To add a filter that directs IP4 packess of priority 3 to queue 3:
ethtool -N <ethX> flow-type ether proto 0x800 vlan 0x600 m 0x1FFF \
action 3 loc 16

VLAN id must be accompanied by mask 0xF000. That is to distinguish
VLAN filter from L2 Ethertype filter with UserPriority since both
User Priority and VLAN ID are passed in the same 'vlan' parameter.
Flow type may be any as it is not matched for VLAN filter.

reserved for vlan filters.

Each slave has it's own receive timestamp filter. But cpts rx/tx
timestamp enable flags are used to allow ts retrieve only for one
user. This limitation causes data path redundancy and setting overlap
if cpsw module is in dual-mac mode for instance.
If rx ts is enabled only for one port - the second interface must expect
every incoming packet to be PTP packet w/o absolutely any reason, and if
it's PTP - do unneeded stuff, as rx filter for second port is not set
and cpts fifo is not supposed to contain appropriate ts event.
That's not correct.
So, to fix control overlap and avoid redundant CPU cycles, the patch
splits rx/tx ts enable flags between network devices. After the patch,
PTP timestamping still should be used for only one port (or PTP id
counter has to be different for both ports as cpts IP is common).

The overflow event is running with 1 jiffy in case if txq is not
empty, but it can be emptied completely only if next tx event
consumes skb or deletes staled skb from the txq. In case of staled
skb, that can happen for some unpredictable reason (the ts event was
lost or timed out), the overflow event can be generated quite long
time consuming CPU w/o reason before next tx event happens. To avoid
it, purge txq before increasing overflow event rate.

Previous to this commit the driver was immediately stopping Tx/Rx
queues when doing the following "echo 0 > sriov_numvfs" and then it was
calling pci_disable_sriov if the VFs are not assigned. This was causing
the VIRTCHNL_OP_DISABLE_QUEUES to fail because it was trying to stop
the queues for a second time.
Fix this by calling pci_disable_sriov before stopping the Tx/Rx queues.
This allows the VIRTCHNL_OP_DISABLE_QUEUES to get processed before the
driver tries to stop the Rx/Tx queues in ice_free_vfs.

Before releasing the VSI, remove the VSI scheduler node. If not,
the node is left in the scheduler tree and, on subsequent load, the
scheduler tree contains the node so it does not set it in vsi_ctx.
This, later, causes the node to not be found in ice_sched_get_free_qparent
which leads to a "Failed to set LAN Tx queue context, error: -1".
To remove the scheduler node, this patch introduces ice_rm_vsi_lan_cfg

only ISDN driver w6692 has a private definition. Move the definition
to pci_ids.h and use it in the r8169 driver too.

The mv88e6161 would sometime fail to probe with a timeout waiting for
the switch to complete an operation. This operation is supposed to
clear the statistics counters. However, due to a read/modify/write,
without the needed mask, the operation actually carried out was more
random, with invalid parameters, resulting in the switch not
responding. We need to preserve the histogram mode bits, so apply a
mask to keep them.

The 6390X family has 8 SERDES interfaces. When ports 9 and 10 are not
using all their SERDES interfaces, the unused ones can be assigned to
ports 2-8. Add support for interrupts from SERDES interfaces connected
to these lower ports.

The 6390X family has 8 SERDES interfaces. This allows ports 9 and 10
to support up to 10Gbps using 4 SERDES interfaces. However, when lower
speeds are used, which need fewer SERDES interfaces, the unused SERDES
interfaces can be used by ports 2-8.
The hardware defaults to ports 9 and 10 having all 4 SERDES interfaces
assigned to them. This only gets changed when the interface is
configured after what the SFP supports has been determined, or the 10G
PHY completes auto-neg.
For hardware designs which limit ports 9 and 10 to one or two SERDES
interfaces, and place SFPs on the lower interfaces, this is too
late. Those ports with SFP should not wait until ports 9/10 are up in
order to get access to the SERDES interface. So change the default
configuration when the driver is initialised. Configure ports 9 and 10
to 1000BaseX, so they use a single SERDES interface, freeing up the
others. They can steal them back if they need them.

The X family variants support additional ports modes, for 10G
operation, which the non-X variants don't have. Add a port_set_cmode()
for non-X variants to enforce this.

Now that 2.5G and 5G can be represented in phydev->advertising and
phydev->lp_advertising, add these two links modes as possible
resolutions to auto negotiation.
