Well it appears that my message never made it to the list the first time (not
in the list archive for December, and no response), so I'm trying again. The
patch applies cleanly to the 2.4.0 kernel (2 line fuzz reported by patch). So,
as long as nothing major has changed in the arp handling while I was on
vacation, it should still be Ok.

Subject: [PATCH] accept ARP's with HW Type of 1 from IEEE802 devices

Patch against linux/net/ipv4/arp.c to accept ARP's with HW Type of 1 from
IEEE802 devices (specifically, Fibre Channel devices). This has been tested
with linux-2.4.0-test9 and linux-2.4.0-test12.
