https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=135178 Colin Percival <cperciva@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |cperciva@FreeBSD.org --- Comment #7 from Colin Percival <cperciva@FreeBSD.org> --- PF is inserting bogus TCP checksums into TSO segments. Some interfaces say "gee, some idiot didn't read the spec" and ignore the checksums, while other interfaces say "hey, this is not a TSO packet" and drop it. The Xen network (at least as implemented in EC2) falls into the second category. -- You are receiving this mail because: You are the assignee for the bug.
