From: Ajit Khaparde Date: Fri, 20 Apr 2018 14:22:02 +0000 (-0700) Subject: net/bnxt: fix mbuf data offset initialization X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=c4fed4ff4fb20dc43036c6874c00846750990704;p=dpdk.git net/bnxt: fix mbuf data offset initialization Initialize mbuf->data_off to RTE_PKTMBUF_HEADROOM after allocation. Without this, it might be possible that the DMA address provided to the HW may not be in sync to what is indicated to the application in bnxt_rx_pkt.
