Details:

Hello, 

This patch (against etharp.c 1.165 and etharp.h 1.46) adds support for static
ARP entries.

Summary of changes:
- update_arp_entry() is now public by the name etharp_update_arp_entry()

- added flag ETHARP_LOCK_ENTRY which controls whether an entry should be
locked and/or updated.

- The update policy for ARP entries has been changed according to
(LOCKED=LOCKED_STABLE):

New state / update?          flags
                                                                             
                      ETHARP_LOCK_ENTRY
Current state
EMPTY            STABLE/update      LOCKED/update
PENDING          STABLE/update      LOCKED/update
STABLE           STABLE/update      LOCKED/update
LOCKED           LOCKED/no update   LOCKED/update


I'm also attaching a log which demonstrates the behaviour (max ARP entries is
set to 10).

Regards,
Marcus
