Subject: net/netvsc: initialize VF spinlock
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=5e811a1a39e650aafc931306b0042837baac0450;p=dpdk.git

net/netvsc: initialize VF spinlock

The VF spinlock was never initialized. It works because it is
in zmalloc'd memory and an unlocked lock on x86 is 0.
But for good practice, all spinlock's should be initialized.
