What u
can do is write down ur own function in the driver rx_interrupt
(rtl8139_rx_interrupt this is w.r.t to 2.4.6 kernel) let the driver alloc the
skb
assign the protocol field etc
etc..
Before
the driver gives the packet to the stack (netif_rx) function call u can have ur
module capturing the packet .
u can
use skb_copy or skb_clone to copy an sk_buff depending on your
requirement.

Lakshmi
