[dpdk-dev] [PATCH] ixgbe: logic change in ixgbe_check_mac_link_vf().

[lee.roberts@hp.com]

From: Lee Roberts <lee.roberts@hp.com>

This patch corrects an issue where "testpmd" run against
ixgbevf ports in the host OS reports speed as 100 Mbps
and half-duplex.

If the link status is still needed, set speed to zero,
change ret_val and goto quick exit.  Otherwise, continue
processing to get the correct link speed.
