Jakub Sitnicki	0b9ad56b1e	selftests/bpf: Use SOCKMAP for server sockets in bpf_sk_assign test ... Update bpf_sk_assign test to fetch the server socket from SOCKMAP, now that map lookup from BPF in SOCKMAP is enabled. This way the test TC BPF program doesn't need to know what address server socket is bound to.

Lorenz Bauer	2d7824ffd2	selftests: bpf: Add test for sk_assign ... Attach a tc direct-action classifier to lo in a fresh network namespace, and rewrite all connection attempts to localhost:4321 to localhost:1234 (for port tests) and connections to unreachable IPv4/IPv6 IPs to the local socket (for address tests). Includes implementations for both TCP and UDP. Keep in mind that both client to server and server to client traffic passes the classifier.
