Implement STBC receive frame statistics.

The AR9280 and later can receive STBC.  This adds some statistics
tracking to count these frames.

A patch to athstats will be forthcoming.
Revert a previous commit - this is causing hardware errors.

I'm not sure why this is failing.  The holding descriptor should be being
re-read when starting DMA of the next frame.  Obviously something here
isn't totally correct.

I'll review the TX queue handling and see if I can figure out why this
is failing.  I'll then re-revert this patch out and use the holding
descriptor again.
This shouldn't have made it into this commit, sorry.

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 @

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.
