description:
Since there was already a test to verify that vlan tag 4096 is
detected as invalid, become the "someone" referred to in the
previous commit log, and add tests for 0 and 4095 as well, and
while here, throw in a few more that might elicit bugs.

And if the shell running the tests is able, add tests of a few
random vlan tags between 2 and 4093 (1 and 4094 are always tested)
to check that anything in range works (well, partially check...)
