7609433eb6 Update the Intel igb driver to version 2.4.0
- 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.

6dfc67e379 Close the race on path ID allocation in xpt_bus_register() if two buses are
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.

c11a15bf8d When processing ACK in tcp_do_segment, use sbcut_locked() instead of
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.

1d2df300e9 - Substitute sbdrop_internal() with sbcut_internal(). The latter doesn't free
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.

f677a9e267 Introduce centralized [X]dialog(1) exit codes to `dialog.subr' and make-use
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).

4cfbfdd4b3 Add "better" MIPS24k and MIPS74k barriers.
* 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.

57778cfec4 Add two new MIPS CPU families - mips24k and mips74k.
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.

4a06a0fe79 Change the behavior of bhyve such that the gdb listening port is opt-in
rather than opt-out.

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
events notifications for those events are enabled.  This log page can
be viewed using:

    nvmecontrol logpage -p 2 <ctrlr id>

Future enhancements may re-enable these notifications on a periodic basis
so that if the notified condition persists, it will continue to be logged.
