Hello All, I'm running 6.0 B3 and noticed TCP checksum errors while using the if_bridge functionality. Disabling the onboard checksum function on the NIC stopped the errors. As a note, the TCP checksum put into the packet was only the checksum (without the final inversion) of the pseudo TCP header as described in RFC 793. Here's info on the card: dmesg | grep em0 em0: <Intel(R) PRO/1000 Network Connection, Version - 2.1.7> port 0xb000-0xb01f mem 0xf2300000-0xf231ffff irq 18 at device 1.0 on pci1 em0: Ethernet address: 00:30:48:84:01:22 em0: Speed:N/A Duplex:N/A I'd be happy to try out any patches if someone knows what's going on.
