- move calls to softdep_setup_pagecache() (which can sleep to allocate
memory) outside the softdep lock.
- replace the softdep_flush_indir() hack (which tries to find another
vnode to fsync when we are holding lots of buffer-cache buffers locked
for long periods of time) with softdep_trackbufs() (which just kicks
the syncer and sleeps under the same circumstances). the former method
had a lock-ordering problem which would occasionally deadlock.
- relax the assertion in softdep_sync_metadata() which says that we should
never see D_ALLOCDIRECT deps for VREG vnodes. it's ok to see those
attached to indirect blocks.
also, there's no need to splbio() while allocating the buffer headers
to which pagecache dependencies are attached, so remove that.
fixes all the problems in PR 19288.
called twice. At least in NetBSD, the detach function is called when the
device is removed, even if the attach function has failed.
This is probably the cause of panics reported in kern/19326.
mach-O header. This is a guess based on what we have on Darwin, we need
to check other Mach systems to see if this value is Darwin specific or not.

LINK_STAT notification for every change of BSSID, so the firmware's
BSSID and the driver's BSSID will get out of sync. This has two
bad affects. First, because the 802.11 framework filters received
packets based on BSSID, many packets can be dropped before the
driver adopts the firmware's BSSID. Second, ifconfig's tells a
misleading BSSID to the operator.
This problem is most apparent in networks where every station does
not hear every other. I reproduce these conditions in an office by
removing/replacing the antennas on my 802.11 cards.
As a solution, in IBSS mode, the driver will ask the firmware for
the BSSID every five seconds. Also, whenever the driver receives
a frame carrying a different BSSID than the driver's BSSID, then
the driver asks the firmware for the BSSID before handing the frame
to ieee80211_input.
