--- Comment #12 from commit-h...@freebsd.org --- A commit references this bug: Author: shurd Date: Fri Oct 5 20:16:20 UTC 2018 New revision: 339207 URL: https://svnweb.freebsd.org/changeset/base/339207 Log: Fix igb corrupting checksums with BPF and VLAN When using a vlan with igb and the vlanhwcsum option, any mbufs which already had the TCP, UDP, or SCTP checksum calculated and therefore don't have the CSUM_[IP|IP6]_[TCP|UDP|SCTP] bits set in the csum_flags field would have the L4 checksum corrupted by the hardware. This was caused by the driver setting E1000_TXD_POPTS_TXSM any time a checksum bit was set OR a vlan tag was present. The patched driver only sets E1000_TXD_POPTS_TXSM when an offload is requested.
