In linux kernel since version 2.6.12  
ARP packet filtering defines a table `filter', which has a series of
rules for simple ARP packet filtering at local input and
local output. This is only needed for arptables-legacy(8).
Neither arptables-nft nor nftables need this to work.

To compile it as a module, choose M here. If unsure, say N.
