Subject: [PATCH] net: fix incorrect L2 length for GRE tunneling packet
Date: Wed, 23 Jul 2025 18:47:10 +0800 [thread overview]
Message-ID: <20250723104710.558623-1-huangdengdui@huawei.com> (raw)
The meaning of L2_len in the parsing result of the rte_net_get_ptype()
is the same as the L2_len field in the mbuf. For tunnel packets,
the L2_len should include protocol header of tunnel packets.
Bugzilla ID: 1754
Fixes: d21d855464ff ("net: support GRE in software packet type parser")
