I'm looking into this bug:
http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/31586
In short, using ng_bridge(4) with de(4) and xl(4) drivers,
they're seeing broken TCP checksums on the wire. It sounds
like there's some delayed TCP checksum hack that is breaking
when doing bridging this way.
Could someone quickly explain how delayed TCP checksums
(or whatever they're called) is supposed to work?
Thanks,
-Archie
