Subject: [dpdk-dev] [PATCH v3] net/iavf: fix QFI field bit check for GTPU EH
Date: Fri,  8 Oct 2021 10:41:43 +0000	[thread overview]
Message-ID: <20211008104143.236289-1-junfeng.guo@intel.com> (raw)
In-Reply-To: <20210929123134.1465507-1-junfeng.guo@intel.com>

If GTPU Extionsion header has no pdu_type setting, the parsed value of
gtp_psc_spec->hdr.type will be 0, which is same as IAVF_GTPU_EH_DWLINK.
Thus, for this case, we should check gtp_psc_mask->hdr.type instead,
to set QFI field bit of GTPU_EH first.

Fixes: cd212c466992 ("net/iavf: fix QFI fields of GTPU UL/DL for flow director")
