There's no problem here. If the interface doesn't support offloading, you need to calculate checksums. Just like in Linux. Check the flags in mbuf and if_hwassist; if anything doesn't match, calculate it software-based. -- You are receiving this mail because: You are on the CC list for the bug.help
