Currently the vsi->vf_id is set only for ICE_VSI_VF and it's left as 0
for all other VSI types. This is confusing and could be problematic
since 0 is a valid vf_id. Fix this by always setting non VF VSI types to
ICE_INVAL_VFID.

The only time you can ever have a rq_last_status is if
a firmware event was somehow reporting a status on the receive
queue, which are generally firmware initiated events or
mailbox messages from a VF. Mostly this struct member was unused.
Fix this problem by still printing the value of the field in a debug
print, but don't store the value forever in a struct, potentially
creating opportunities for callers to use the wrong struct member.

The driver previously printed it's PCI address in
the name field for the pci resource, which when displayed
via /proc/iomem, would print the same thing twice.
It's more useful for debugging to see the driver name, as
most other modules do.

The driver would occasionally miss that there were outstanding
descriptors to clean when exiting busy/napi poll. This issue has
been in the code since the introduction of the ice driver.
Attempt to "catch" any remaining work by triggering a software
interrupt when exiting napi poll or busy-poll. This will not
cause extra interrupts in the case of normal execution.
This issue was found when running sfnt-pingpong, with busy
poll enabled, and typically with larger I/O sizes like > 8192,
the program would occasionally report > 1 second maximums
to complete a ping pong.

The ice driver has support for adaptive interrupt moderation, an
algorithm for tuning the interrupt rate dynamically. This algorithm
is based on various assumptions about ring size, socket buffer size,
link speed, SKB overhead, ethernet frame overhead and more.
The Linux kernel has support for a dynamic interrupt moderation
algorithm known as "dimlib". Replace the custom driver-specific
implementation of dynamic interrupt moderation with the kernel's
algorithm.
The Intel hardware has a different hardware implementation than the
originators of the dimlib code had to work with, which requires the
driver to use a slightly different set of inputs for the actual
moderation values, while getting all the advice from dimlib of
better/worse, shift left or right.
The change made for this implementation is to use a pair of values
for each of the 5 "slots" that the dimlib moderation expects, and
the driver will program those pairs when dimlib recommends a slot to
use. The currently implementation uses two tables, one for receive
and one for transmit, and the pairs of values in each slot set the
maximum delay of an interrupt and a maximum number of interrupts per
second (both expressed in microseconds).
There are two separate kinds of bugs fixed by using DIMLIB, one is
UDP single stream send was too slow, and the other is that 8K
ping-pong was going to the most aggressive moderation and has much
too high latency.
The overall result of using DIMLIB is that we meet or exceed our
performance expectations set based on the old algorithm.

Introduce several new helpers for writing ITR and GLINT_RATE
registers, and refactor the code calling them. This resulted
in removal of several duplicate functions and rolled a bunch
of simple code back into the calling routines.
In particular this removes some code that was doing both
a store and a set in a helper function, which seems better
done as separate tasks in the caller (and generally takes
less lines of code even with a tiny bit of repetition).

Normally, the bootloader will already initialize the MAC address
registers of the ENETC and the driver will just use them or generate a
random one, if it is not initialized.
Add a new way to provide the MAC address: via device tree. Besides the
usual 'mac-address' property, there is also the possibility to fetch it
via a NVMEM provider. The sl28 board stores the MAC address in the SPI
NOR flash OTP region. Having this will allow linux to fetch the MAC
address from there without being dependent on the bootloader.
No in-tree boards have the device tree properties set, thus for these,
this is a no-op.

Setting 10G without autonegotiation is invalid according to

If 1G autonegotiation can't complete for quite a time, but there is
signal in line, switch line interface type to 10GBase-R, if supported,
in hope for link to be established.
And vice versa. If 10GBase-R link can't be established for quite a time,
and autonegotiation is enabled, and there is signal in line, switch line
interface type to appropriate 1G mode, i.e. 1000Base-X or SGMII, if

Currently each packet inserted in eswitch is tagged with a internal
metadata to indicate source vport. Metadata tagging is not always
needed. Metadata insertion is needed for multi-port RoCE, failover
between representors and stacked devices. In many other cases,
metadata enablement is not needed.
Metadata insertion slows down the packet processing rate of the E-switch
when it is in switchdev mode.
Below table show performance gain with metadata disabled for VXLAN
offload rules in both SMFS and DMFS steering mode on ConnectX-5 device.
----------------------------------------------
| steering | metadata | pkt size | rx pps |
| mode | | | (million) |
----------------------------------------------
| smfs | disabled | 128Bytes | 42 |
----------------------------------------------
| smfs | enabled | 128Bytes | 36 |
----------------------------------------------
| dmfs | disabled | 128Bytes | 42 |
----------------------------------------------
| dmfs | enabled | 128Bytes | 36 |
----------------------------------------------
Hence, allow user to disable metadata using driver specific devlink
parameter. Metadata setting of the eswitch is applicable only for the
switchdev mode.
Example to show and disable metadata before changing eswitch mode:
$ devlink dev param show pci/0000:06:00.0 name esw_port_metadata
pci/0000:06:00.0:
name esw_port_metadata type driver-specific
values:
cmode runtime value true
$ devlink dev param set pci/0000:06:00.0 \
name esw_port_metadata value false cmode runtime
$ devlink dev eswitch set pci/0000:06:00.0 mode switchdev

During the handling of CAN bus errors, a CAN error SKB is allocated
using alloc_can_err_skb(). Even if the allocation of the SKB fails,
the function continues in order to do the stats handling.
All access to the can_frame pointer (cf) should be guarded by an if
statement:
if (cf)
However, the increment of the rx_bytes stats:
netdev->stats.rx_bytes += cf->can_dlc;
dereferences the cf pointer and was not guarded by an if condition
leading to a NULL pointer dereference if the can_err_skb() function
failed.
Replacing the cf->can_dlc by the macro CAN_ERR_DLC (which is the
length of any CAN error frames) solves this NULL pointer dereference.

This patch adds support for tc flower hardware offload on the ingress
path. Shared filter blocks are supported by sharing a single ACL table
between multiple ports.
The following flow keys are supported:
- Ethernet: dst_mac/src_mac
- IPv4: dst_ip/src_ip/ip_proto/tos
- VLAN: vlan_id/vlan_prio/vlan_tpid/vlan_dei
- L4: dst_port/src_port
As per flow actions, the following are supported:
- drop
- mirred egress redirect
- trap
Each ACL entry (filter) can be setup with only one of the listed
actions.
A sorted single linked list is used to keep the ACL entries by their
order of priority. When adding a new filter, this enables us to quickly
ascertain if the new entry has the highest priority of the entire block
or if we should make some space in the ACL table by increasing the
priority of the filters already in the table.

Change the default ACL trap rule for STP frames to have the highest
priority.
In the same ACL table will reside both default rules added by the driver
for its internal use as well as rules added with tc flower. In this
case, the default rules such as the STP one that we already have should
have the highest priority.
Also, remove the check for a full ACL table since we already know that
it's sized so that we don't hit this case. The last thing changes is
that default trap filters will not be counted in the acl_tbl's num_rules
variable since their number doesn't change.
