- Replace XXX with Note: in several cases where observations are made about
future functionality rather than problems or bugs.
- Remove an XXX comment about byte order and au_to_ip() -- IP headers must

node would send every outgoing frame to the "compress" hook.
Packets received on the "compress" hook were expected to be
compressed and PROT_COMPD tag was put on them unconditionally.
After this commit an alternative compression mode can be set.
In this mode the node doesn't put the PROT_COMPD, the compressor
should put it itself. This is important for such kind of
compressors, that can submit uncompressed frames.
Before this commit, if the decompression is enabled, the ng_ppp(4)
node would send and incoming frame to the "decompress" hook
only if it has the PROT_COMPD proto tag on it.
After this commit an alternative decompression mode can be set.
In this mode the node sends all the incoming packets to the
decompression hook. This is important for such kind of compressors
that need uncompressed packets too, to keep their library in sync.
These new features will be used in new version of mpd4, and in new
compressor nodes.

mainly involves removing all __CC_SUPPORTS___INLINE__ ifdefs. These
ifdefs are even less needed for amd64 than for i386, but the i386
atomic.h never had them. The ifdefs here were just an optimization
of obsolescent compatibility cruft (__inline) for a null set of
compilers. I think null sets of compilers should only be supported
in cases where this is more than an optimization, doesn't require
extensive ifdefs, and only involves not-so-obsolescent compatibility
cruft (plain inline here).
o mark 11g mode support on finding 11g or pure 11g (OFDM-only)
channels; was requiring pure 11g which caused some contortions
in drivers that manually setup their channel lists
These functions are used a lot for mutexes, so this reduces the text
size of an average kernel by about 0.75%. This wasn't intended to
be a significant optimization, but it somehow increased the maximum
number of packets per second that can be transmitted by my bge hardware
from 320000 to 460000 (this benchmark is CPU-bound and remarkably
sensitive to changes in the text section).
Details: we would prefer to leave the result of the cmpxchg in %al,
but cannot tell gcc that it is there, so we have to convert it to an
integer register. We converted to %al, then to %[re]ax, but the
latter step is usually wasted since gcc usually only wants the condition
code and can recover it from %al just as easily as from %[re]ax. Let
gcc promote %al in the few cases where this is needed.
Nearby style fixes;
- let gcc manage the load of `res', and don't abuse `res' for a copy of `exp'
- don't echo `res's name in comments
- consistently spell the condition code as 'e' after comparison for equality
- don't hard-code %al anywhere except in constraints
- for the version that doesn't use cmpxchg, there is no requirement to use
%al anywhere, so don't hard-code it in the constraints either.
Style non-fix:
- for the versions that use cmpxchg, keep using "a" (was %[re]ax, now %al)
for the main output operand, although this is not required. The input
and output operands that use the "a" constraint are now decoupled, and
this makes things clearer except for the reason that the output register
is hard-coded. It is now just a hack to tell gcc that the input "a" has
been clobbered without increasing the number of operands.
o change handling of regdomain-related mib knobs so they can be set
post-attach: regdomain, countrycode, outdoor, and xchanmode; the
hal will not permit changing the regdomain but we expose it for now
o on regdomain/countrycode change recalculate the channel list and
push it to the net80211 layer (NB: looks to need more tweaking)
o setup rate tables for half/quarter rate channels
o honor half/quarter rate channel configs when changing channels
o honor half/quarter rate channel configs when setting the slot time
o use hack/nonstandard channel numbering scheme for the public safety
band to avoid overlapping 2.4G channels on dual-band cards
o remove setup of ic_sup_rates; the net80211 layer can do this for us
and it simplifies handling of half/quarter rate channels
Tested only in Public Safety Band with cards that have RF5112.
o add hack/nonstandard channel mapping for public safety band channels to
mirror kernel (temporary until we have proper 802.11 state)
o change ieee80211_mhz2ieee to take channel flags (unused right now)
While here do some minor fixups like using IEEE80211_IS_CHAN_ANYG.
