1beab2699f [siba] use the correct SPROM offsets.
I transcribed the linux ssb offsets and .. didn't pick up that our SIBA
SPROM code has an offset of 0x1000.

This fixes a bunch of odd parsing values that showed up when I tried
using a newer NIC.  The NIC still doesn't yet work but now the SPROM
values are right.

Oops!

4b1c046953 [bwn] add initial 5xx firmware API support
* Add the new TX/RX frame formats;
* Use the right TX/RX format based on the frame info;
* Disable the 5xx firmware check, since now it should
  somewhat work (but note, we don't yet use it unless
  you manually add ucode11/initvals11 from the 5.x driver
  to bwn-kmod-firmware;

* Misc: update some comments/debugging now I know what's
  actually going on.

Tested:

* BCM4321MC, STA mode, both 4xx and 666 firmware, DMA mode

TODO:

* The newer firmware ends up logging "warn: firmware state (0)";
  not sure yet what's going on there.  But, yes, it still works.
  I'm committing this via a BCM4321MC, 11a station, firmware
  rev 666.

596f2a146d Import the 'iflib' API library for network drivers. From the author:
"iflib is a library to eliminate the need for frequently duplicated device
independent logic propagated (poorly) across many network drivers."

Participation is purely optional.  The IFLIB kernel config option is
provided for drivers that want to transition between legacy and iflib
modes of operation.  ixl and ixgbe driver conversions will be committed
shortly.  We hope to see participation from the Broadcom and maybe
Chelsio drivers in the near future.

d82dbf711e Micro-optimize sleepq_broadcast().
- Avoid a conditional branch on the return value of sleepq_resume_thread()
  by ORing its return value into the boolean wakeup_swapper. This is
  consistent with other sleepqueue functions which just pass this return
  value to their caller.
- sleepq_resume_thread() unconditionally removes the thread from its queue,
  so there's no need to maintain a pointer to the next element in the queue.

e877de9591 Rework managing hotplug commands with command completions.
Previously the command completion interrupt would post any pending
command immediately before pcib_pcie_hotplug_update() had been
run to inspect the current status.  Now, the command completion
interrupt merely clears the flag and stops the timer assuming that
the caller is always going to call pcib_pcie_hotplug_update() to
generate the next hotplug command if one is needed.

While here, fix a bug for systems with command completion where the
old (existing) value was written to the slot control register instead
of the new value.  This fixes the complaint about a missing hotplug
interrupt on my T400.

eab5a1b232 Document the formatting requirements of location and pnpinfo strings.
devd requires location and pnpinfo strings generated by bus drivers
to be formatted as a list of name=value keypairs.  Non-conforming
bus drivers cause devd to mis-parse device events for these buses.

Note that this documents the desired requirements.  devctl_safe_quote()
doesn't yet escape backslash characters, and devd doesn't handle escaped
characters in quoted values.
