I find a lot references of the function neigh_release(), can you direct
me to the one that releases a staled arp entry? Thanks.

I'm reading the code about arp protocol. It seems like the kernel uses
the neigh_table structure to keep track of caches, right?
yes.
There should
be some code that remove the stale entries in the cache, but I didn't
find the code that does this job. Does anyone have an idea?
look at neigh_release(...) and neigh_destroy(...). basically,
neigh_release(...) decrements the reference count of a neighbor, and
neigh_destroy(...) frees it when this reference count reaches zero.

In the beginning was the lambda, and the lambda was with Emacs, and
Emacs was the lambda.
