From c4fed4ff4fb20dc43036c6874c00846750990704 Mon Sep 17 00:00:00 2001 From: Ajit Khaparde Date: Fri, 20 Apr 2018 07:22:02 -0700 Subject: [PATCH] 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.
