- 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.

registered simultaneously. Due to topology unlock between the ID allocation
and the bus registration there is a chance that two buses may get the
same IDs. That is supposed reason of lock assertion panic in CAM during
initial bus scanning after new iscsid initiates two sessions same time.

sbdrop_locked() to cut acked mbufs from the socket buffer. Free this
chain a batch manner after the socket buffer lock is dropped.
This measurably reduces contention on socket buffer.

mbufs, but return chain of free mbufs to a caller. Caller can either reuse
them or return to allocator in a batch manner.
- Implement sbdrop()/sbdrop_locked() as a wrapper around sbcut_internal().
- Expose sbcut_locked() for outside usage.

throughout the bsdconfig(8) code. While we're here, add an explicit argument
to lvalue-seeking invocations of "return" that previously had no argument.
Also, consolidate a single instance of double-newline and remove some
comments that are no longer required (given increased readability with new
exit codes).

* 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.

o Allow this to work with "nodevice random" by fixing where the MALLOC pool is defined.
o Fix the explicit reseed code. This was correct as submitted, but in the project branch doesn't need to set the "seeded" bit as this is done correctly in the "unblock" function.
o Remove some debug ifdeffing.
o Adjust comments.

cmd_lst and rbis members of struct ahci_port from integers to pointers.
Also surround a pow-of-2 test expression with parentheses to clarify it,

I replaced the sx_* locks that Arthur used with regular mutexes; this turned out the be the wrong thing to do as the locks need to be sleepable. Revert this folly.

Prior to this change if the "-g" option was not specified then a listening
socket for tunneling gdb packets would be opened at port 6466. If a second
virtual machine is fired up, also without the "-g" option, then that would
fail because there is already a listener on port 6466.
After this change if a gdb tunnel port needs to be created it needs to be
explicitly specified with a "-g <portnum>" command line option.

This prevents repeated notifications of the same event.
Status of these events may be viewed at any time by viewing the
SMART/Health Info Page using nvmecontrol, whether or not asynchronous

Future enhancements may re-enable these notifications on a periodic basis
