https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D270285 Michael Tuexen <tuexen@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |tuexen@freebsd.org --- Comment #1 from Michael Tuexen <tuexen@freebsd.org> --- The two bytes after the IPv4 packet are padding. It is required, since the = an ethernet frame must be at least of 64 bytes. The last 4 bytes are frame che= ck sequence, so there must be 60 bytes. The IPv4 packet is 44 bytes, plus 6 by= tes source, 6 bytes dest, 2 bytes upper layer information makes 58 bytes. There= fore 2 bytes is appended. See https://en.wikipedia.org/wiki/Ethernet_frame So the packet looks correct to me. --=20 You are receiving this mail because: You are the assignee for the bug.=
