Hi, I get TCP/UDP checksum errors with fxp(4). I noticed it after using Wireshark today:
Checksum: 0xac18 [incorrect, should be 0xfbc7 (maybe caused by
checksum offloading?)]
for example.
If I understand it more or less correctly, checksum offloading is
performed by or with help of the NIC - only for TCP and UDP, where the
checksum fails exactly...
I didn't found a way to disable it, so I assume it's a bug in the
driver... I don't know exactly which infos I must provide additionally
to the following, so don't hesitate to ask more :)
Used NIC:
fxp0: <Intel 82550 Pro/100 Ethernet> port 0xa400-0xa43f mem
0xfb030000-0xfb030fff,0xfb000000-0xfb01ffff irq 16 at device
