Subject: [rfc] new sk_buff member: hwstamp

Hi everybody,

In our Linux port we added a new sk_buff member, hwstamp, to store a hardware 
generated timestamp for received packets. The hardware can also insert  
hardware timestamps in the payload on the TX path and can have the RX / TX 
clocks synchronized. We use this infrastructure to compute one-way delays 
with high precision (20ns resolution).

I know that adding new members to such heavily used structures like the skb is 
viewed harshly - especially for such exotic cases as the one described above. 
So, would such a patch be considered for inclusion? Or maybe there is a 
better way of doing the above?

Thanks,
tavi
