[dpdk-dev] [PATCH v2] net/qede: fix advertising link speed capability

[Rasesh Mody <Rasesh.Mody@cavium.com>]

From: Harish Patil <harish.patil@qlogic.com>

Fix to advertise device's link speed capability based on NVM
port configuration instead of returning driver supported speeds.

Fixes: 95e67b479506 ("net/qede: add 100G link speed capability")
