From: Manish Lachwani <m_lachwani@yahoo.com> Date: Wed, 4 Sep 2002 07:34:57 -0700 (PDT) I am trying to implement the TCP checksum offload support using Intel e1000/3com 3c996b-t in Linux 2.4.19. Does this version of the kernel support transmit h/w checksum offloading? Is there any patch I need to apply to the driver or kernel to get this feature to work? It's already supported for e1000 cards. Perhaps you are using only normal send/sendmsg/write system calls to send data over sockets, in that case TX checksum offload isn't used (there is no gain). It starts getting used once you start using sendfile() to transmit your data. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
