Subjectarp cache tuning in 2.4.x (x >= 10)
(please CC, I'm not on the list)
(a CC to would be appreciated to)

For quite some time now, I have "Neighbour table overflow." on
one of our router (serving more than 1000 boxes).

A bunch of google search gave me to answer :
1 - playing with /proc/sys/net/ipv4/neigh/default/gc_thres*
2 - configure CONFIG_ARPD and find an user-space arp daemon.

Can any of you guys give more explanations on both solutions?
Mainly :
- what are sane value for 1),
- is 2 really a "sane" solution (from :
"This code is experimental and also obsolete").
