Subject: net/hinic: optimize mbuf allocation
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=abd41e3d004746753d9198b3896bcb919f601167;p=dpdk.git

net/hinic: optimize mbuf allocation

When port start, driver needs to alloc mbuf resource to fill Rx
queue bd section, replace rte_mbuf_raw_alloc function to
rte_pktmbuf_alloc_bulk with initialized mbuf structure to avoid
some structures being used without initialization.
