Subject: net/ixgbe: fix link status synchronization on BSD
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=0012111a3d879b0b0e27d14a841e2a729545727d;p=dpdk.git

net/ixgbe: fix link status synchronization on BSD

DPDK does not implement interrupt mechanism on BSD,
so force NIC status synchronization.

Fixes: dc66e5fd01b9 ("net/ixgbe: improve link state check on VF")
