I want to specify filter to exclude list of protocols (arp, tcp) i.e. filter is [not(arp or tcp)].

Packets are mixed from untagged vlan and tagged vlan. How can I specify it since filter:(not arp and not tcp) doesnt work as it works only on untagged vlan packets.

I am using libpcap and I want to filter both tagged and untagged packets.

For example, exp: <filter> or (vlan or <filter>) works for "arp or tcp" But same expression dont work if filter : not(arp or tcp)
