The fix is pretty simple; in l2tp_xmit_ipv6_csum, change CHECKSUM_COMPLETE 
to CHECKSUM_UNNECESSARY (or CHECKSUM_NONE), as that will prevent the 
incoming sk_buff's ->csum value from being used (it's not correct).  I'm 
travelling at the moment, so I may not have time to respin the patch until 
Wednesday, but if I can, I will try to find the time this evening.
