[PATCH net-next 0/5][pull request] Intel Wired LAN Driver Updates 2022-08-18 (ice)

[Tony Nguyen]

This series contains updates to ice driver only.

Jesse and Anatolii add support for controlling FCS/CRC stripping via
ethtool.

Anirudh allows for 100M speeds on devices which support it.

Sylwester removes ucast_shared field and the associated dead code related
to it.

Mikael removes non-inclusive language from the driver.

The following are changes since commit e34cfee65ec891a319ce79797dda18083af33a76:
  stmmac: intel: remove unused 'has_crossts' flag
and are available in the git repository at:

[PATCH net-next 1/5] ice: Implement control of FCS/CRC stripping

[Tony Nguyen]

From: Jesse Brandeburg <jesse.brandeburg@intel.com>

The driver can allow the user to configure whether the CRC aka the FCS
(Frame Check Sequence) is DMA'd to the host as part of the receive
buffer.  The driver usually wants this feature disabled so that the
hardware checks the FCS and strips it in order to save PCI bandwidth.

Control the reception of FCS to the host using the command:
ethtool -K eth0 rx-fcs <on|off>

The default shown in ethtool -k eth0 | grep fcs; should be "off", as the
hardware will drop any frame with a bad checksum, and DMA of the
checksum is useless overhead especially for small packets.

Testing Hints:
test the FCS/CRC arrives with received packets using
tcpdump -nnpi eth0 -xxxx
and it should show crc data as the last 4 bytes of the packet. Can also
use wireshark to turn on CRC checking and check the data is correct.

[PATCH net-next 2/5] ice: Implement FCS/CRC and VLAN stripping co-existence policy

[Tony Nguyen]

From: Anatolii Gerasymenko <anatolii.gerasymenko@intel.com>

Make sure that only the valid combinations of FCS/CRC stripping and
VLAN stripping offloads are allowed.

You cannot have FCS/CRC stripping disabled while VLAN stripping is
enabled - this breaks the correctness of the FCS/CRC.

If administrator tries to enable VLAN stripping when FCS/CRC stripping is
disabled, the request should be rejected.

If administrator tries to disable FCS/CRC stripping when VLAN stripping
is enabled, the request should be rejected if VLANs are configured. If
there is no VLAN configured, then both FCS/CRC and VLAN stripping should
be disabled.

Testing Hints:
The default settings after driver load are:
- VLAN C-Tag offloads are enabled
- VLAN S-Tag offloads are disabled
- FCS/CRC stripping is enabled

Restore the default settings before each test with the command:
ethtool -K eth0 rx-fcs off rxvlan on txvlan on rx-vlan-stag-hw-parse off
tx-vlan-stag-hw-insert off

Test 1:
Disable FCS/CRC and VLAN stripping:
ethtool -K eth0 rx-fcs on rxvlan off
Try to enable VLAN stripping:
ethtool -K eth0 rxvlan on

Expected: VLAN stripping request is rejected

Test 2:
Try to disable FCS/CRC stripping:
ethtool -K eth0 rx-fcs on

Expected: VLAN stripping is also disabled, as there are no VLAN
configured

Test 3:
Add a VLAN:
ip link add link eth0 eth0.42 type vlan id 42
ip link set eth0 up
Try to disable FCS/CRC stripping:
ethtool -K eth0 rx-fcs on

Expected: FCS/CRC stripping request is rejected

[PATCH net-next 5/5] ice: remove non-inclusive language

[Tony Nguyen]

From: Mikael Barsehyan <mikael.barsehyan@intel.com>

Remove non-inclusive language from the driver where
possible; replace "master" with "primary"; replace
"slave" with "secondary".
