AFAIK that ethernet chipset is not particularly advanced. ARP is not a
function of the card itself, nor the low-level driver. ARP resolution works
via broadcasting queries for an IP address to all nodes on the network.
Then, the node that has that address is supposed to send back a unicast
response to the requesting node. The requesting node then stores the MAC/IP
association in its ARP table. Someone correct me if I missed anything
important or don't really understand this as well as I think.
If you are having arp table problems there must be something else not
working properly.

What causes the lockups? How often? I have an RTL 8139 in use.
However, I have noticed something strange. I must keep "outbound" traffic
flowing or they forget their ARP table for some strange reason. I keep an
outbound ping running... If i dont, and there is no network activity on
the box, it is unresponsive via network, but hopping on the console and
starting another ping session brings it back to life. (I also have to do
this on my machines with older RTL cards, using the ne2k-pci driver)
So far, uptime of box and kernel ver with RTL cards is:
Linux xxxxx 2.2.19 #22 Wed Jun 20 18:12:16 PDT 2001 i686 unknown
9:42am up 13 days, 6:57, 6 users, load average: 0.00, 0.00, 0.00
