[Bug 270285] Network issue with very small frames (tcp, padded)

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=270285

--- Comment #8 from Michael Tuexen <tuexen@freebsd.org> ---
Please note that the padding is NOT part of the IP packet. Therefore, no node
should consider at as being part of the IP packet or even the TCP payload. I
guess some node is looking at the Ethernet frame length to deduce the IP packet
length, instead of looking at the length field in the IP header. Network cards
did this wrong in the past and failed hardware checksum checks since they took
the padding into consideration where they shouldn't. This doesn't help here,
but might give a hint where things can go wrong.
