[dpdk-dev] [PATCH 14/15] net/bnxt: fix mbuf flags for PTP packets in vector mode Rx

[Ajit Khaparde]

From: Kalesh AP <kalesh-anakkur.pura...@broadcom.com>

PKT_RX_IEEE1588_PTP and PKT_RX_IEEE1588_TMST flags need to be set
in the offload flags for the received pkt in case of PTP offload.

Fixes: bc4a000f2f53c ("net/bnxt: implement SSE vector mode")
