selftests/bpf: Add various more tcx test cases
0e1fa14 
Add several new tcx test cases to improve test coverage. This also includes
a few new tests with ingress instead of clsact qdisc, to cover the fix from
commit dc644b5 ("tcx: Fix splat in ingress_destroy upon tcx_entry_free").

selftests/bpf: Test bpf_mprog query API via libbpf and raw syscall
f255aca 
Add a new test case which performs double query of the bpf_mprog through
libbpf API, but also via raw bpf(2) syscall. This is testing to gather
first the count and then in a subsequent probe the full information with
the program array without clearing passed structs in between.

selftests/bpf: Test query on empty mprog and pass revision into attach

Add a new test case to query on an empty bpf_mprog and pass the revision
directly into expected_revision for attachment to assert that this does
succeed.

selftests/bpf: Add selftests for netkit
c338997 
Add a bigger batch of test coverage to assert correct operation of
netkit devices and their BPF program management:

  # ./test_progs -t tc_netkit
  [...]
  [    1.166267] bpf_testmod: loading out-of-tree module taints kernel.
  [    1.166831] bpf_testmod: module verification failed: signature and/or required key missing - tainting kernel
  [    1.270957] tsc: Refined TSC clocksource calibration: 3407.988 MHz
  [    1.272579] clocksource: tsc: mask: 0xffffffffffffffff max_cycles: 0x311fc932722, max_idle_ns: 440795381586 ns
  [    1.275336] clocksource: Switched to clocksource tsc
