3c59x.c modified for time measurement / code included

[Guilhem Tardy <guilhem_tardy@xxxxxxxxx>]

Hi all,

I should be able to access skb->mac.{ethernet, raw} ahter eth_type_trans(skb,
dev), but nevertheless I used skb->data in the code below. At this point, only
a series of consecutive numbers are written for test purpose, but the result is
nil: I get all but what is expected when I tcpdump packets received on this
port. I thought that the error could reside in the filter on UDP & port, but it
seems right. Any idea?

Guilhem.
