Fixed a panic that occurs when bringing up an interface on 57710/57711
running very old bootcode versions.
Fixed how bool is defined for those who have been using this code on older
versions of FreeBSD.

I changed it to use if_transmit a while ago but apparently with monitor
mode the if_transmit method is overridden.
This is (mostly) a workaround until a more permanent solution can be
found.

when they return to real mode. This can cause a fault when BTX re-enters
protected mode after the BIOS mode returns.

The device name was incorrect due to a specific function we ported
from the Linux driver that is not FBSD compatible. This resulted
with a false sysctl registration and some more problematic issues.
The patch basically revokes it all together.

really belong to it. Such vnodes, with the pointers to other vnodes
v_objects, are typically instantiated by the bypass filesystems.
Invalidating mappings of other vnode pages and the pages is wrong,
since reclamation of the upper vnode does not imply that lower vnode
is reclaimed too.
One of the consequences of the improper reclamation was destruction of
the wired mappings of the lower vnode pages, triggering miscellaneous
assertions in the VM system.

threads still performing unlocked accesses to it.
Grow the table exponentially instead of increasing its size by
sizeof(long) * 8 chunks when overflowing. This mode significantly
reduces the total memory use for the processes consuming large numbers
of the file descriptors which open them one by one.

- This version has support for the new Intel Avoton systems,
including 2.5Gb support, further it now has IPv6/TSO6 support as
well. Shared code has been updated where necessary as well. Thanks
to my new assistant Eric Joyner for doing the transmit path changes
to bring in the IPv6/TSO6 support. Thanks to Gleb for catching the
one bug and change needed in NETMAP.

* the mips74k cores only need EHB (which is 'sll $0, $0, 3')
here; NOPs don't actually work.
* add EHB as the last NOP for the default barriers/hazards;
that is "better" behaviour and should work on a wider
variety of processors.
This allows the existing (icky) TLB code to work, allowing
the AR9344 SoC (mips74k) to actually get through kernel startup.
Tested:
* AR9344 SoC - (mips74k)
* AR9331 SoC - (mips24k)
TODO:
* test on mips4k CPUs, just to be sure.
* document that sll $0, $0, 3 is actually "EHB" and that it
falls back to being a NOP for pre-mips32r1.
* mips24k has an errata that we currently don't correctly explicitly
state - ie, that after DERET/ERET, the only valid instruction is
a NOP.

They're both different cores:
* mips24k is an 8-stage pipeline, mips32r1 ABI, non-superscalar core.
* mips74k is a dual-issue 15-stage superscalar design, mips32r2 ABI.
They have different sets of quirks and bugs; these #define entries
will be used to work around these.
Now, strictly speaking, we should have CPU ABI families (mips32r1, mips32r2,
etc) and CPU core types (mips4k, mips24k, mips74k, etc.) But this is the
starting point of that particular tidy-up.
