>Description:
Watching outgoing udp packets (from openser) on port 5060 via tshark, I was finding that they were just about all saying that there was a checksum error. Looking at the source of if_bge.c, I found that the 5700 B0 chipset had a similar problem, so I extended the fix to all the variants of the 5703, as I didn't know which of the 5703s are broken. This is replicable on a Dell 2650. Below is a relevant portion of the dmesg regarding the interfaces. You'll find a patch attached to this pr, but as I'm not anything close to a programmer, I wouldn't doubt if someone would have a better way of doing this.
