I'm sad to say that it doesn't

/usr/src/atm/at/at76c503.c: In function `ieee80211_to_eth':
/usr/src/atm/at/at76c503.c:3919: error: invalid lvalue in assignment

at76c503.c:
3919: eth_hdr(skb) = eth_hdr_p;

It seams that one can not assign a value to the eth_hdr(skb)
function...?

The eth_hdr() definition is added in
include/linux/if_ether.h:
----
[...]
/*
 *      This is an Ethernet frame header.
 */

struct ethhdr {
        unsigned char   h_dest[ETH_ALEN];       /* destination eth addr */
        unsigned char   h_source[ETH_ALEN];     /* source ether addr    */
        unsigned short  h_proto;                /* packet type ID field */
} __attribute__((packed));                                                                                                       

#ifdef __KERNEL__                                                                                                                
#include <linux/skbuff.h>                                                                                                        

static inline struct ethhdr *eth_hdr(const struct sk_buff *skb)
{
        return (struct ethhdr *)skb->mac.raw;
}                                                                                                                                
#endif

One need to put it there in another way i suppose. Directly in skb->mac.raw.
In my digging I noticed there's alot of nice functions for juggling with
skb's in net/core/skbuff.c . But that's a bit too advanced for me. =(

Thanks! =)
