the tables of ARP rules in the Linux kernel. These rules inspect
the ARP frames which they see. arptables is analogous to the iptables
user space tool, but is less complicated.

%description legacy
The arptables is a user space tool used to set up and maintain
the tables of ARP rules in the Linux kernel. These rules inspect
the ARP frames which they see. arptables is analogous to the iptables
user space tool, but is less complicated.

Note that it is considered legacy upstream since nftables provides the same
functionality in a much newer code-base. To aid in migration, there is
arptables-nft utility, a drop-in replacement for the legacy one which uses
nftables internally. It is provided by iptables-arptables package.

arptables systemd services

This package provides the systemd arptables service that has been split
out of the base package for better integration with alternatives.

%build
# Makefile uses $(KERNEL_DIR) to redefine where to look for header files.
# But when it's set to standard system include directory gcc ignores it
# (see gcc(1)). It however looks that the code is not ready for using 
# system headers (instead included ones) so we don't use this option.
