Are:

net.ipv4.neigh.default.gc_thresh1=1024
net.ipv4.neigh.default.gc_thresh2=2048
net.ipv4.neigh.default.gc_thresh3=4096

or

net.ipv4.neigh.default.gc_thresh1 = 16384
net.ipv4.neigh.default.gc_thresh2 = 28672
net.ipv4.neigh.default.gc_thresh3 = 32768

sane changes to always make? whats a safe default? does this only cover IPv4? if so do we need to cover something similar for IPv6?
