Backporting 2.6 stack features

[Steve Modica <modica@xxxxxxx>]

Hi All,

Has anyone been working on backporting features of the 2.6 stack and 
tg3.c driver?
I've incoporated some small changes to the driver and mod_timer to 
reduce contention on some locks, but I'd also like to do the following:
1. get rid of do_cscum (which requires the newer sk_buff)
2. reduce contention in __wake_up
3. reduce contention in skb_release_data
