Re: [PATCH] Ethernet Bridging: Enable Hardware Checksumming

[Stephen Hemminger <shemminger@xxxxxxxx>]

Here is a somewhat different patch from 2.6.12-rc4-bridge
http://developer.osdl.org/shemminger/patches/2.6.12-rc4-bridge/

The bridge doesn't need locking, or checksumming and can allow highdma
buffers; all of which are handled by net/core/dev.c if needed.
