This is set to the SI_SUB_* value before executing any VNET_SYSINIT
or VNET_SYSUNINT. While good for debugging especially VNET teardown
problems having a chance to know at which level during teardown we are,
it will also be used to identify to detcted a "stable state"
(as in fully up and running) later on.

to perform a lookup, e.g. from within interrupt context.

lookup in the ipfw_install_state().
Also remove MATCH_* macros, they are defined in ip_fw_private.h as enum.

That was both redundant as zfs_znode_sa_init() already does the job and
insufficient as the root vnode can be reached via other means.

gfs code is (almsot) completely agnostic of FreeBSD VFS locking, so it
does not handle doomed but not yet dead vnodes and may return them.
Check for those vnodes here and retry a lookup.
Note that ZFS and gfs have additional protections that ensure that a
parent vnode of the current vnode is never doomed.
The fixed problem is an occasional failure to lookup a 'snapshot' or
'shares' directories under .zfs.
Note that for the above reason all uses of zfsctl_root_lookup() are
better be replaced with VOP_LOOKUP.

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!
return value when it could return 1 (indicating we should stop).
Fix a few instances of pager_open() / pager_close() not being called.
Actually use these routines for the environment variable printing code
I just committed.
a slightly non-standard %S that's more useful in the UEFI environment,
so ignore printf errors. There's no good cast to use. We'll need to
revisit this in the future.
* 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.

"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.

- 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.

It has no counterpart among the other lock primitives and has been a
no-op for years. Mutex consistency checks are generally done whenver
INVARIANTS is enabled.
Greatly reduce the locked instructions and reduce number of inner loops.
