[bpf-next,0/2] Enable bpf_setsockopt() on ktls enabled sockets.

This patchset implements a change to bpf_setsockopt() which allows
ktls enabled sockets to be used with the SOL_TCP level. This is
necessary as when ktls is enabled, it changes the function pointer of
setsockopt of the socket, which bpf_setsockopt() checks in order to
make sure that the socket is a TCP socket. Checking sk_protocol
instead of the function pointer will ensure that bpf_setsockopt() with
the SOL_TCP level still works on sockets with ktls enabled.

Kui-Feng Lee (2):
  bpf: Check the protocol of a sock to agree the calls to
    bpf_setsockopt().
  selftests/bpf: Calls bpf_setsockopt() on a ktls enabled socket.
