When the accept queue is full print the number of already pending
new connections instead of by how many we're over the limit, which
is always 1.

According to the documentation, on Linux, cancel_delayed_work() does not
do drain (flush_workqueue() in Linux terms) but instead returns true if
the work was removed before it is run, or false otherwise.

Simulate this by removing the taskqueue_drain() and return the value
derived from taskqueue_cancel()'s return value.

This would solve a witness warning caused by calling taskqueue_drain()
with a non-sleepable lock held, like:

taskqueue_drain with the following non-sleepable locks held:
exclusive rw lle (lle) r = 0 (0xfffffe001450b410) locked @

Make errbuf optional, so if a caller is not interested in an error

Add the ability to change the vlan operation mode.

This adds a vlan capability field to etherswitch_info structure and some
definitions of ports flags.

It adds the support to global config parameters which right now is used
only to switch between the vlan modes, but it is intended to be extended
to support the setup of others parameters (STP, mirror, etc.).

Add vlan configuration support to etherswitchcfg.

This adds the support to the config keyword (vlan operation mode), ports
flags, prints the vlan mode and vlan capabilities. It also adds some basic
information to usage() and support the keyword 'help' as a shortcut to
usage(). The manual page is also updated with the new options.

Fix the ukswitch code to work with the new vlan changes:

* Fix API changes;
* remove unused code;
* Allow some switches to be used that don't expose a set of PHY
  registers for the CPU facing port (eg the ADM6996 for the Ubiquiti
  Routerstation.)

Modify the routerstation config to use ukswitch for now.

Until an ADM6996 driver shows up, this allows for the two switch
ports to be used.
