Elsukov AuthorDate: 2022-11-10 09:34:40 +0000 Commit: Gordon Tetlow CommitDate: 2023-02-08 16:30:38 +0000 ixgbe: workaround errata about UDP frames with zero checksum Intel 82599 has errata related to IPv4 UDP frames with zero checksum. It reports such datagrams with L4 integrity errors in IXGBE_XEC register. And after afb1aa4e6df2 commit such errors are reported via IFCOUNTER_IERRORS. This confuses users, since actually all frames are handled correctly by the system. To workaround the problem, let's ignore the XEC register value for 82599 cards for now.
