Synopsis: [bge] [patch] bge has checksum problems on the 5703 chipset
State-Changed-From-To: open->analyzed
State-Changed-By: kris
State-Changed-When: Tue Dec 25 14:11:09 UTC 2007
State-Changed-Why:
This is most likely not a bug unless you can confirm the bad checksums
from *ANOTHER* machine on the same link. When hardware checksum
offload is in use, the OS does not compute the checksum (it happens in
the NIC as the packet is transmitted) so tcpdump sees a "wrong"
checksum. See the tcpdump manpage.
