src: Introduce socket matching
For now it can only match sockets with IP(V6)_TRANSPARENT socket option
set. Example:
table inet sockin {
chain sockchain {
type filter hook prerouting priority -150; policy accept;
socket transparent 1 mark set 0x00000001 nftrace set 1 counter packets 9 bytes 504 accept
}
}
