0f0819525b Add support for the Atmel SAM9XE familiy of microcontrollers, which
consist of a ARM926EJ-S processor core with up to 512 Kbytes of on-chip

d6c65d276e Converted the remainder of the NIC drivers to use the mii_attach()
introduced in r213878 instead of mii_phy_probe(). Unlike r213893 these
are only straight forward conversions though.

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.

3064f0530b - Initialize callout before it is used in atestop() during attach.
- Reorder detach so that ether_ifdetach() is called first.  This removes
  the race that ATE_FLAG_DETACHING closed, so that flag can be removed.
- Trim a duplicate clearing of IFF_DRV_RUNNING.

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.

10170e4559 Since we create a DMA tag "mtag" for TX map with bus_dmamap_create(),

o Fix the packet statistics
	o Make sure we set the FD bit when in full duplex
	o Improve TX side efficency by eliminating a data copy for
	  unfragmented mbufs (the hardware can't do s/g).
	o Minor busdma pedantry
	o better comments in some places, more XXX in others
	o Minor style nits.

This solves a problem I was seeing where I'd get no ethernet when not
booting with a NFS root.  Well, unless I unplugged the cable and
plugged it back in first so I'd get the same up down up messages I get
for NFS root...

Thanks to sam and scottl for suggestions on making this driver more
efficient through better use of approrpiate APIs.

aee1351504 Carefully note the RMII bit in the config register at attach time.
The boot loader is supposed to leave this bit set to the right value
for the board.  If this bit was set at attach time, use it to init the
config register correctly.

Note: this means the boot loader has to properly initialize it.

d5d776c16b Resurrect Skyeye support :
Add a new option, SKYEYE_WORKAROUNDS, which as the name suggests adds
workarounds for things skyeye doesn't simulate. Specifically :
- Use USART0 instead of DBGU as the console, make it not use DMA, and           manually provoke an interrupt when we're done in the transmit function.
- Skyeye maintains an internal counter for clock, but apparently there's
no way to access it, so hack the timecounter code to return a value which
is increased at every clock interrupts. This is gross, but I didn't find a
better way to implement timecounters without hacking Skyeye to get the
counter value.
- Force the write-back of PTEs once we're done writing them, even if they
are supposed to be write-through. I don't know why I have to do that.
