shmif: change behaviors about link states
- Change the link state to UP on ifconfig linkstr
- This behavior emulates physical devices
- Change the link state to UNKNOWN on ifconfig -linkstr just in case
- Reject sending/receiving packets if the link state is DOWN
- Permit to send/receive packets on UNKNOWN, which is required
to unbreak some ATF tests written in C
shmif: support media
It enables to link-down shmif by ifconfig media none and link-up
again by media auto.
ifconfig: show link state on -v
We could guess it through "media" or "status" output, however, we
sometimes want to know it directly for debugging or testing.
It is shown only if the -v option is specified.
tests: add tests for shmif
The test file is placed under tests/net, not tests/rump/rumpnet,
to leverage utility functions provided for tests in there.
shmem(4): Fix typo in comment: AFT -> ATF.
Also fix grammar (if I understood correctly what this meant: rump
servers written in C, rather than set up via shell scripts around
rump_server invoking ifconfig).
No functional change intended.
