SVN rev 218289 on 2011-02-04 17:49:55Z by yongari
Disable TX IP checksum offloading for RTL8168C controllers. The
controller in question generates frames with bad IP checksum value
if packets contain IP options. For instance, packets generated by
ping(8) with record route option have wrong IP checksum value. The
controller correctly computes checksum for normal TCP/UDP packets
though.
There are two known RTL8168/8111C variants in market and the issue
I observed happened on RL_HWREV_8168C_SPIN2. I'm not sure
RL_HWREV_8168C also has the same issue but it would be better to
assume it has the same issue since they shall share same core.
RTL8102E which is supposed to be released at the time of
RTL8168/8111C announcement does not have the issue.
