o remove HAL_CHANNEL; convert the hal to use net80211 channels; this
mostly involves mechanical changes to variable names and channel
attribute macros
o gut HAL_CHANNEL_PRIVATE as most of the contents are now redundant
with the net80211 channel available
o change api for ath_hal_init_channels: no more reglass id's, no more outdoor
indication (was a noop), anM contents
o add ath_hal_getchannels to have the hal construct a channel list without
altering runtime state; this is used to retrieve the calibration list for
the device in ath_getradiocaps
o add ath_hal_set_channels to take a channel list and regulatory data from
above and construct internal state to match (maps frequencies for 900MHz
cards, setup for CTL lookups, etc)
o compact the private channel table: we keep one private channel
per frequency instead of one per HAL_CHANNEL; this gives a big
space savings and potentially improves ani and calibration by
sharing state (to be seen; didn't see anything in testing); a new config
option AH_MAXCHAN controls the table size (default to 96 which
was chosen to be ~3x the largest expected size)
o shrink ani state and change to mirror private channel table (one entry per
frequency indexed by ic_devdata)
o move ani state flags to private channel state
o remove country codes; use net80211 definitions instead
o remove GSM regulatory support; it's no longer needed now that we
pass in channel lists from above
o consolidate ADHOC_NO_11A attribute with DISALLOW_ADHOC_11A
o simplify initial channel list construction based on the EEPROM contents;
we preserve country code support for now but may want to just fallback
to a WWR sku and dispatch the discovered country code up to user space
so the channel list can be constructed using the master regdomain tables
o defer to net80211 for max antenna gain
o eliminate sorting of internal channel table; now that we use ic_devdata
as an index, table lookups are O(1)
o remove internal copy of the country code; the public one is sufficient
o remove AH_SUPPORT_11D conditional compilation; we always support 11d
o remove ath_hal_ispublicsafetysku; not needed any more
o remove ath_hal_isgsmsku; no more GSM stuff
o move Conformance Test Limit (CTL) state from private channel to a lookup
using per-band pointers cached in the private state block
o remove regulatory class id support; was unused and belongs in net80211
o fix channel list construction to set IEEE80211_CHAN_NOADHOC,
IEEE80211_CHAN_NOHOSTAP, and IEEE80211_CHAN_4MSXMIT
o remove private channel flags CHANNEL_DFS and CHANNEL_4MS_LIMIT; these are
now set in the constructed net80211 channel
o store CHANNEL_NFCREQUIRED (Noise Floor Required) channel attribute in one
of the driver-private flag bits of the net80211 channel
o move 900MHz frequency mapping into the hal; the mapped frequency is stored
in the private channel and used throughout the hal (no more mapping in the
driver and/or net80211)
o remove ath_hal_mhz2ieee; it's no longer needed as net80211 does the
calculation and available in the net80211 channel
o change noise floor calibration logic to work with compacted private channel
table setup; this may require revisiting as we no longer can distinguish
channel attributes (e.g. 11b vs 11g vs turbo) but since the data is used
only to calculate status data we can live with it for now
o change ah_getChipPowerLimits internal method to operate on a single channel
instead of all channels in the private channel table
o add ath_hal_gethwchannel to map a net80211 channel to a h/w frequency
(always the same except for 900MHz channels)
o add HAL_EEBADREG and HAL_EEBADCC status codes to better identify regulatory
problems
o remove CTRY_DEBUG and CTRY_DEFAULT enum's; these come from net80211 now
o change ath_hal_getwirelessmodes to really return wireless modes supported
by the hardware (was previously applying regulatory constraints)
o return channel interference status with IEEE80211_CHANSTATE_CWINT (should
change to a callback so hal api's can take const pointers)
o remove some #define's no longer needed with the inclusion of
<net80211/_ieee80211.h>

Inside the kernel, the minor() function was responsible for obtaining
the device minor number of a character device. Because we made device
numbers dynamically allocated and independent of the unit number passed
to make_dev() a long time ago, it was actually a misnomer. If you really
want to obtain the device number, you should use dev2udev().
We already converted all the drivers to use dev2unit() to obtain the
device unit number, which is still used by a lot of drivers. I've
noticed not a single driver passes NULL to dev2unit(). Even if they
would, its behaviour would make little sense. This is why I've removed
the NULL check.
Ths commit removes minor(), minor2unit() and unit2minor() from the
kernel. Because there was a naming collision with uminor(), we can
rename umajor() and uminor() back to major() and minor(). This means
that the makedev(3) manual page also applies to kernel space code now.
I suspect umajor() and uminor() isn't used that often in external code,
but to make it easier for other parties to port their code, I've
increased __FreeBSD_version to 800062.
can cope with a result buffer of NULL in the "Final" function, we cannot.
Thus pass in a temporary buffer long enough for either md5 or sha1 results
so that we do not panic.

section included a lot of stuff that did not belong there.
So split the block in multiple components each around the relevant stuff.
This said, I wonder if building a kernel where SYSCTL_NODE is not
defined is supported at all.

fragments in the file system by fragment (block) number. This new
mode does the necessary arithmetic to generate absolute fragment
numbers rather than than the cg-relative numbers printed in the default
mode.
If -f is passed once, contiguous fragment ranges are collapsed into
an X-Y format as free block lists are currently printed in regular
dumpfs output, but if specified twice, all block numbers are printed
individually, allowing both compact and more script-friendly
representation.
This proves quite handy when attempting to recover deleted data, as it
allows exclusion of non-deleted data from blocks searched.

o max antenna gain
o driver private opaque data
Note this grows the size of a channel to 16 bytes; which makes the
default channel table 4Kbytes (up from 3Kbytes).
o change ioctl's that pass channel lists in/out to handle variable-size
arrays instead of a fixed (compile-time) value; we do this in a way
that maintains binary compatibility
o change ifconfig so all channel list data structures are now allocated
to hold MAXCHAN entries (1536); this, for example, allows the kernel
to return > IEEE80211_CHAN_MAX entries for calls like IEEE80211_IOC_DEVCAPS
the ISO tables, mark them accordingly
o add sku's for handling 900MHz cards
o add opaque struct defs and change []'s to *'s so this file can be
included w/o requiring all of net80211 to be pulled in
o make CTRY_DEBUG and CTRY_DEFAULT public
extended attributes since FreeBSD 5, make the following semantic
changes:
- Don't update the inode modification time (mtime) when extended
attributes (and hence also ACLs) are added, modified, or removed.
- Don't update the inode access tie (atime) when extended attributes
(and hence also ACLs) are queried.
This means that rsync (and related tools) won't improperly think
that the data in the file has changed when only the ACL has changed.
Note that ffs_reallocblks() has not been changed to not update on an
IO_EXT transaction, but currently EAs don't use the cluster write
routines so this shouldn't be a problem. If EAs grow support for
clustering, then VOP_REALLOCBLKS() will need to grow a flag argument
to carry down IO_EXT to UFS.

throughput?).
Usual moving of code with no changes from ipfw2.c to the
newly created files, and addition of prototypes to ipfw2.h
I have added forward declarations for ipfw_insn_* in ipfw2.h
to avoid a global dependency on ip_fw.h
In this episode:
- introduce a common header with a minimal set of common definitions;
- bring the main() function and options parser in main.c
- rename the main functions with an ipfw_ prefix
No code changes except for the introduction of a global variable,
resvd_set_number, which stores the RESVD_SET value from ip_fw.h
and is used to remove the dependency of main.c from ip_fw.h
(and the subtree of dependencies) for just a single constant.
