selftests/net: test sk_filter support for SKF_NET_OFF on frags
Verify that a classic BPF linux socket filter correctly matches
packet contents. Including when accessing contents in an
skb_frag.
1. Open a SOCK_RAW socket with a classic BPF filter on UDP dport 8000.
2. Open a tap device with IFF_NAPI_FRAGS to inject skbs with frags.
3. Send a packet for which the UDP header is in frag[0].
4. Receive this packet to demonstrate that the socket accepted it.
