linux kernel 2.6.9-rc4, skb->mac.ethernet => eth_hdr(skb) issues.

Hello, you who this might concern.

I have been trying to compile with the following results:

--snip--
/usr/src/atm/at76c503a/at76c503.c: In function `ieee80211_to_eth':
/usr/src/atm/at76c503a/at76c503.c:3903: error: union has no member named
`ethernet'
--snip--

at76c503.c - 3902-3903:
  eth_hdr = (struct ethhdr *)(skb->data-sizeof(struct ethhdr));
	  skb->mac.ethernet = eth_hdr;

Related changes to the kernel i found in this file:
/usr/src/linux/include/linux/if_ether.h

Found on google; This error and sollution is most likely because 
of the same changes in the linux kernel, need different sollution
though:

If I was abit better at this level of network-coding I could have made 
a patch, but I failed at that. My patched driver never returned any pings. 
And my conclusion to that is that I screwed up the ethernet-header. :-(

Hopefully this is no match for the maintainers of this driver and they
can fix this so that the forthcoming kernel 2.6.9 will work as a charm.

Thank's for your great work! :-)
