Subject: [dpdk-dev] [PATCH v2 1/2] net/ixgbe: enable x550 flexible byte filter
Date: Tue, 25 Dec 2018 13:44:47 +0800 [thread overview]
Message-ID: <1545716688-34608-2-git-send-email-wei.zhao1@intel.com> (raw)
In-Reply-To: <1545716688-34608-1-git-send-email-wei.zhao1@intel.com>
There is need for users to use flexible byte filter on x550.
x550 support IP mode and tunnel mode flexible byte filter.
tunnel mode flexible byte filter is used for vxlan packets
and so on. It can be used combined with FDIR tunnel filter.
By now, ixgbe PMD flow parer code do not support tunnel mode
flexible byte filter for x550, So I have to enable it in function
ixgbe_parse_fdir_filter_tunnel(). Although IP mode flexible byte
filter parser is support in function ixgbe_parse_fdir_filter_normal(),
but some flow like "flow create 0 ingress pattern raw pattern is
0xab / end actions queue index 3 / end" need to be support, so
parser code also need change a little.
This patch enable all of these feature.
Fixes: 82fb702077f6 ("ixgbe: support new flow director modes for X550")
Fixes: 11777435c727 ("net/ixgbe: parse flow director filter")
