Subject: [PATCH v2] net/ice: fix Tx Checksum offload
Date: Sun, 12 Dec 2021 14:35:20 +0000 [thread overview]
Message-ID: <20211212143520.2356157-1-kevinx.liu@intel.com> (raw)
In-Reply-To: <20211208095626.85026-1-kevinx.liu@intel.com>
The tunnel packets is missing some information after Tx forwarding.
In ice_txd_enable_offload, when set tunnel packet Tx checksum
offload enable, td_offset should be set with outer l2/l3 len instead
of inner l2/l3 len.
In ice_txd_enable_checksum, td_offset should also be set with outer
l3 len.
This patch fix the bug that the checksum engine can forward Ipv4/Ipv6
tunnel packets.
Fixes: 28f9002ab67f ("net/ice: add Tx AVX512 offload path")
Fixes: 17c7d0f9d6a4 ("net/ice: support basic Rx/Tx")
