Kernel headers - linux-atm userspace build broken by recent change; __be16 undefined

[Andrew Walrond <andrew@walrond.org>]

Don't know exactly when this change went in, but it's not in 2.6.18.3 
and is in 2.6.19.2+

 $ diff linux/include/linux/if_arp.h linux-2.6/include/linux/if_arp.h
133,134c133,134
<       unsigned short  ar_hrd;         /* format of hardware address   */
<       unsigned short  ar_pro;         /* format of protocol address   */

>       __be16          ar_pro;         /* format of protocol address   */

<       unsigned short  ar_op;          /* ARP opcode (command)         */

>       __be16          ar_op;          /* ARP opcode (command)         */


This causes the linux-atm userspace compile to fail like this:

In file included from arp.c:19:
/usr/include/linux/if_arp.h:133: error: expected 
specifier-qualifier-list before '__be16'

I guess if_arp.h needs to include include/linux/byteorder/big_endian.h?
