76039bc84f The r48589 promised to remove implicit inclusion of if_var.h soon. Prepare
to this event, adding if_var.h to files that do need it. Also, include
all includes that now are included due to implicit pollution via if_var.h

e50d35e6c6 Add new tunable 'net.link.ifqmaxlen' to set default send interface
queue length. The default value for this parameter is 50, which is
quite low for many of today's uses and the only way to modify this
parameter right now is to edit if_var.h file. Also add read-only
sysctl with the same name, so that it's possible to retrieve the
current value.

7cf545d0a1 - Add a private timer to drive the transmit watchdog instead of using
if_watchdog and if_timer.
- Fix some issues in detach for sn(4), ste(4), and ti(4).  Primarily this
  means calling ether_ifdetach() before anything else.

eb956cd041 Use if_maddr_rlock()/if_maddr_runlock() rather than IF_ADDR_LOCK()/
IF_ADDR_UNLOCK() across network device drivers when accessing the
per-interface multicast address list, if_multiaddrs.  This will
allow us to change the locking strategy without affecting our driver
programming interface or binary interface.

For two wireless drivers, remove unnecessary locking, since they
don't actually access the multicast address list.

1851bd711a While reviewing if_sn in an attempt to understand network drivers
better, I discovered sn doing too many pointer dereferences.  This
driver would do silly things like:
	sn_foo(struct ifnet *ifp)
	{
		struct sn_softc *sc = ifp->if_softc;

		sc->ifp->mumble
		/* Other stuff */
	}

while /* other stuff */ usually needed sc, the extra deref isn't
needed.  Eliminate a few dozen of them.

ad4f426ef6 Make sure that we call if_free(ifp) after bus_teardown_intr. Since we
could get an interrupt after we free the ifp, and the interrupt
handler depended on the ifp being still alive, this could, in theory,
cause a crash.  Eliminate this possibility by moving the if_free to
after the bus_teardown_intr() call.

13f4c340ae Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and
IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to
ifnet.if_drv_flags.  Device drivers are now responsible for
synchronizing access to these flags, as they are in if_drv_flags.  This
helps prevent races between the network stack and device driver in
maintaining the interface flags field.

Many __FreeBSD__ and __FreeBSD_version checks maintained and continued;
some less so.

cec14ad556 Noticed that NetBSD's sm driver has the PSION GOLDCARD listed, so list
that since I can't test it directly.  The driver also lists the EM1144
as being supported, but in reality it isn't.  The EM1144-T,
{XJ,CC}{3288,3336} have the SMC chips in them, but aren't conformant MFC
cards, so they need their own driver.

Also, it does little harm to list the 8020BT, so remove #if 0.

fc74a9f93a Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
   To enforce this ac_enaddr has been renamed to _ac_enaddr.
 - The second argument to ether_ifattach is now always the mac address
   from driver private storage rather than sometimes being ac_enaddr.

fbfb97942e It turns out that the module dependency on pccard is in error. Since
there's not dependencies on pccard symboles, such a dependency is not
necessary.  This means that drivers that have multiple attachments can
not drag bogus devices into the kernel at load time.

We can't (yet) do this with pci and isa.  Drivers written for them
actually do seem to have symbols that depend on these busses'
implementation code.

ndis not touched until other things can be tested.

0318355d0e Remove improper use of if_addrhead in device drivers to check
if the link-level address has been initialized already.

The majority of modern drivers never does this and works fine, which
makes me think that the check is totally unnecessary and a residue
of cut&paste from other drivers.

This change is done to simplify locking because now almost none of the
drivers uses this field. The exceptions are "ct" "ctau" and "cx"
where i am not sure if i can remove that part.
