Hello, all. I am going through the TCP/IP code in the Linux kernel (Kernel 2.4.7-10). I have two Broadcom cards integrated in the motherboard. They support Scatter-gather and checksum offload. But it seems Kernel 2.4.7-10 doesn't support zero-copy and checksums are still calculated before packets go to the card. Could anyone tell me which staple kernel version support zero-copy? Thanks a lot. Jiaying -- Kernelnewbies: Help each other learn about the Linux kernel. Archive: http://mail.nl.linux.org/kernelnewbies/ FAQ: http://kernelnewbies.org/faq/
