[dpdk-dev] [PATCH] ixgbe: fix link speed detection of ixgbevf

[Choonho Son <choonho.son@gmail.com>]

Link speed of virtual function is detected as default speed(100Mbps, half-duplex).
Before checking VF link, get_link_status must be set.

Checking link status
PMD: ixgbe_check_for_rst_vf(): ixgbe_check_for_rst_vf
done
PMD: ixgbe_check_for_rst_vf(): ixgbe_check_for_rst_vf
Port 0 Link Up - speed 100 Mbps - half-duplex
