Ironically I dont know if I have the issue as I have always routinely disab= led checksum offloading on vtnet since day 1 following advice from pfSense developers, luckily performance is ok. But it is only today I think I have discovered the reason for this advice. --=20 You are receiving this mail because: You are on the CC list for the bug.=
