AR8216: make ARL age time configurable
The default TTL for address resolution table entries is 5 minutes for all members of the AR8216 family. This can cause issues if e.g. Wifi clients roam to another AP and their MAC appears on another switch port suddenly. Then the client may not be reachable until the old ARL entry expires. I would have expected the switch to invalidate old entries if it detects the same MAC on another port. But that's not the case. Therefore make the TTL for ARL entries configurable. The effective TTL will always be a multiple of 7 seconds. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> SVN-Revision: 48913
