[dpdk-dev] [PATCH 6/6] net/bnx2x: fix optic module verification

[Rasesh Mody <rmody@marvell.com>]

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.
