Subject: [PATCH v3] net/ice: fix pattern check for FDIR parser
Date: Wed, 22 Dec 2021 16:11:38 +0800 [thread overview]
Message-ID: <20211222081138.1617225-1-junfeng.guo@intel.com> (raw)
In-Reply-To: <20211222080852.1604018-1-junfeng.guo@intel.com>
FDIR rules with masks are not supported in current code. Thus add
pattern check for IPv4/UDP/TCP/SCTP addr/port to terminate the FDIR
programming stage.
Fixes: 1b71ed2cdd5d ("net/ice: refactor flow pattern parser")
Cc: stable@dpdk.org
