Subject: net/bnxt: maintain mbuf alloc failure counter per queue
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=472193a710567bfe245f697cdf688968fa485b02;p=dpdk.git

net/bnxt: maintain mbuf alloc failure counter per queue

Currently we have a single counter for mbuf alloc failure.
Make it per RxQ instead.
