Subject: [PATCH] net/ice: fix error forwarding IPv6 VXLAN packet
Date: Thu, 9 Dec 2021 02:08:38 +0000 [thread overview]
Message-ID: <20211209020838.87188-1-kevinx.liu@intel.com> (raw)
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.
This patch fix the bug that the checksum engine can forward tunnle
packets.
Fixes: 28f9002ab67f ("net/ice: add Tx AVX512 offload path")
