[patch 035/101] Clear TCP segmentation offload state in ipt_REJECT

2007-03-07 Thread Greg KH
From: Herbert Xu <[EMAIL PROTECTED]> [NETFILTER]: Clear GSO bits for TCP reset packet The TCP reset packet is copied from the original. This includes all the GSO bits which do not apply to the new packet. So we should clear those bits. Spotted by Patrick McHardy. Signed-off-by: Herbert Xu <[E

TCP Segmentation Offload

2001-05-13 Thread Aviv Greenberg
Hi All, There is a nice feature (I saw it on 3Com EtherLink Server NIC cards) called "TCP Segmentation Offload". Which means that the stack is presented with a larger MTU than eth, and the NIC produces smaller tcp segments. More info at M$ http://www.microsoft.com/HWDEV/network/tasko
