https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=194314 --- Comment #7 from Garrett Cooper <ngie@FreeBSD.org> --- (In reply to Eric Joyner from comment #6) > Does that mean only the sizes of struct m_hdr and struct m_pkthdr change, or > do you change MSIZE as well? The size of struct m_ext and struct m_hdr is larger than stock FreeBSD, with certain compile-time options. However, you can technically tweak MSIZE though so it's less than 160, which would also reproduce the situation. That scenario seems kind of silly though. -- You are receiving this mail because: You are the assignee for the bug.
