patch 'net/ice/base: fix DSCP PFC TLV creation' has been queued to stable release 21.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/01/22. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/0255526a1bb113101b3b7428adf54df2eb0972f9

Thanks.

Subject: [PATCH] net/ice/base: fix DSCP PFC TLV creation

[ upstream commit bc696378a9fd6ed00c8f35556e0b6e5bd171465c ]

When creating the TLV to send to the FW for configuring DSCP
mode PFC, the PFCENABLE field was being masked with a 4 bit
mask (0xF), but this is an 8 bit bitmask for enabled classes
for PFC.  This means that traffic classes 4-7 could not be
enabled for PFC.

Remove the mask completely, as it is not necessary, as we are
assigning 8bits to an 8 bit field.

Fixes: 8ea78b169603 ("net/ice/base: support L3 DSCP QoS")
