[dpdk-stable] patch 'net/bnx2x: fix optic module verification' has been queued to LTS release 18.11.2

[Kevin Traynor]

Hi,

FYI, your patch has been queued to LTS release 18.11.2

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 05/13/19. 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-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/90baad67611a2ddfd9731cb1d441ea13f7014020

Thanks.

Kevin Traynor

Subject: [PATCH] net/bnx2x: fix optic module verification

[ upstream commit 5a6af6baa8c64ab31bd457b12be1f5173194bec6 ]

Enable the optic module vendor and part number verification from driver
by setting appropriate flags. Link handling module in conjunction with
FW performs optic module verification.

Without this fix the SFP is powered down and the link doesn't come up,
if module verification is enforced in nvram setting.

Fixes: 540a211084a7 ("bnx2x: driver core")
