X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=76469c0631adbc007e89f70f2503ed9b5e3f7f8b;p=dpdk.git

net/i40e: support request any number of queues

Before this patch, VF must request a specific queues(1/2/4/8/16) with
DPDK PF. This patch align the number of requested queues to next power
of 2. So VF can request any number queues from 1 to 16.
