The ng_ksocket(4) functionality is very fragile as it interfaces with
kernel socket code in unusual way. It definitely needs a test suite.
Start one with a test that tests UDP over IPv4.
Any netgraph operation requires root priveleges. Some tests in the
directory already mark themselves with 'atf_tc_set_md_var(conf,
"require.user", "root");' which creates a lot of pasted code. Some tests
don't mark self. For this particular directory a blanket metadata setting
in the Makefile is acceptable, imho.
Test functionality of ng_vlan_rotate(4):
- Rotate 1 to 9 stagged vlans in any possible direction and length
- Rotate random combinations of ethertypes (8100, 88a8, 9100)
- Automatic reverse rotating for backward data flow
- Test too many and to few vlans

Provide a framework of functions to test various netgraph modules.
Tests contain:
- creating, renaming, and destroying nodes
- connecting and removing hooks
- sending and receiving data
- sending ASCII messages
- errors can be passed for indiviual inspection or fail the test
