src: add netdev family support
This patch adds support for the new 'netdev' table. So far, this table allows
you to create filter chains from ingress.
The following example shows a very simple base configuration with one table that
contains a basechain that is attached to the 'eth0':
# nft list table netdev filter
table netdev filter {
chain eth0-ingress {
type filter hook ingress device eth0 priority 0; policy accept;
}
}
You can test that this works by adding a simple rule with counters:
# nft add rule netdev filter eth0-ingress counter
