patch 'net/bnxt: get maximum supported multicast filters count' has been queued to stable release 21.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/26/22. 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/377a9a8197501f086bc537db195de84b2a0be5d5

Thanks.

Kevin

Subject: [PATCH] net/bnxt: get maximum supported multicast filters count

[ upstream commit bc9b2c20d29eea7cf1fbf098d69016bc4edb8c2e ]

The HWRM_FUNC_QCAPS response indicates the maximum number
of multicast filters that can be supported by this function
on the RX side.

Fixed to use this value instead of the hard coded value 16.

Fixes: d69851df12b2 ("net/bnxt: support multicast filter and set MAC addr")
