[Intel-wired-lan] [PATCH AUTOSEL 6.6 074/104] ice: fix ICE_AQ_VSI_Q_OPT_RSS_* register values

[Sasha Levin]

From: Ahmed Zaki <ahmed.zaki@intel.com>

[ Upstream commit 20f73b60bb5c276cee9b1a530f100c677bc74af8 ]

Fix the values of the ICE_AQ_VSI_Q_OPT_RSS_* registers. Shifting is
already done when the values are used, no need to double shift. Bug was
not discovered earlier since only ICE_AQ_VSI_Q_OPT_RSS_TPLZ (Zero) is
currently used.

Also, rename ICE_AQ_VSI_Q_OPT_RSS_XXX to ICE_AQ_VSI_Q_OPT_RSS_HASH_XXX
for consistency.

[Intel-wired-lan] [PATCH AUTOSEL 6.6 085/104] ice: fix pre-shifted bit usage

[Sasha Levin]

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

[ Upstream commit 7173be21ae29ef50ada42fd4464056a9d3f55bb3 ]

While converting to FIELD_PREP() and FIELD_GET(), it was noticed that
some of the RSS defines had *included* the shift in their definitions.
This is completely outside of normal, such that a developer could easily
make a mistake and shift at the usage site (like when using
FIELD_PREP()).

Rename the defines and set them to the "pre-shifted values" so they
match the template the driver normally uses for masks and the member
bits of the mask, which also allows the driver to use FIELD_PREP
correctly with these values. Use GENMASK() for this changed MASK value.

Do the same for the VLAN EMODE defines as well.

[Intel-wired-lan] [PATCH AUTOSEL 6.6 101/104] i40e: Fix VF disable behavior to block all traffic

[Sasha Levin]

From: Andrii Staikov <andrii.staikov@intel.com>

[ Upstream commit 31deb12e85c35ddd2c037f0107d05d8674cab2c0 ]

Currently, if a VF is disabled using the
'ip link set dev $ETHX vf $VF_NUM state disable' command, the VF is still
able to receive traffic.

Fix the behavior of the 'ip link set dev $ETHX vf $VF_NUM state disable'
to completely shutdown the VF's queues making it entirely disabled and
not able to receive or send any traffic.

Modify the behavior of the 'ip link set $ETHX vf $VF_NUM state enable'
command to make a VF do reinitialization bringing the queues back up.
