One of the features that prevented us from fixing some of the TTY
consumers to work once again, was an interface that allowed consumers to
do the following:
- `Sniff' incoming data, which is used by the snp(4) driver.
- Take direct control of the input and output paths of a TTY, which is
used by ng_tty(4), ppp(4), sl(4), etc.
There's no practical advantage in committing a hooks layer without
having any consumers. In P4 there is a preliminary port of snp(4) and
thompsa@ is busy porting ng_tty(4) to this interface. I already want to
have it in the tree, because this may stimulate others to work on the
remaining modules.

According to style(9), function argument names should only be omitted
for prototypes that are exported to userspace. This means we should
document the function arguments in the TTY header files, because they
are only used in userspace.
While there, change the type of the buffer argument of
ttydisc_rint_bypass() to `const void *' instead of `char *'.

It seems this script was broken because of the SYSINIT changes and a
rather awkward variable initialisation. For some reason the
make_device_driver.sh script is also broken, related to BUS_SETUP_INTR.
I have no experience with FreeBSD's interrupt handling, so I hope
someone else is willing to take a look at that shell script.

IPv4 address, first drop the udbinfo and inpcb locks, which will otherwise
be recursed. This leads to a potential minor race, but is preferable to a
deadlock when acquiring a read lock after a write lock on the inpcb.

o change ieee80211_parse_htcap and ieee80211_parse_htinfo to save only
internal state obtained from the ie's; no dynamic state such as
ni_chw is altered
o add ieee80211_ht_updateparams to parse ht cap+info ie's and update
dynamic node state
o change ieee80211_ht_node_init to not take an htcap ie that is parsed;
instead have the caller make a separate call as one caller wants to
parse the ie while another wants to parse both cap+info ie's and
update state so can better do this with ieee80211_ht_updateparams
These changes fix sta mode state handling where the node's channel
width was shifted to ht20/ht40 prematurely.
don't duplicate this. These are setup according to the role of the
node--the bss node for ap and adhoc modes need to use parameters
that are the least common denomimator of all nodes in the bss;
otherwise we are setting up params for a station joining a bss and
we select those according to the capabilities of the station.
This stuff needs more work as we do extra work due to having setup
in common code paths shared by nodes using both roles.
o don't use the key index to identify when the driver has been
asked to allocate a key slot, use an explicit flag; allows
drivers to force s/w fallback for entries in the global table
o change callback api to allocate driver resources for a crypto key:
- de-const the key parameter so drivers can muck with the flags
- on callback failure don't automatically try to setup s/w crypto;
instead the driver must now mark the key entry for s/w crypto and
the caller will re-attach the cipher module
NB: api change permits drivers more control over fallback to s/w
crypto (e.g. based on a limited number of h/w key slots)
For receive:
o explicitly tag rx frames w/ M_AMPDU instead of passing frames through
the reorder processing according to the node having HT and the frame
being QoS data
o relax ieee80211_ampdu_reorder asserts to allow any frame to be passed
in, unsuitable frames are returned to the caller for normal processing;
this permits drivers that cannot inspect the PLCP to mark all data
frames as potential ampdu candidates with only a small penalty
o add M_AMPDU_MPDU to identify frames resubmitted from the reorder q
For transmit:
o tag aggregation candidates with M_AMPDU_MPDU
o fix the QoS ack policy set in ampdu subframes; we only support immediate
BA streams which should be marked for "normal ack" to get implicit block
ack behaviour; interestingly certain vendor parts BA'd frames with the
11e BA ack policy set
o do not assign a sequence # to aggregation candidates; this must be done
when frames are submitted for transmit (NB: this can/will be handled
better when aggregation is pulled up to net80211)
properly; was doing this only on a change in the protection mode
so the advertised protection mode in the beacon would oscillate.

o use txa_start to form the addba request and purge txa_seqstart
o fill txa_start before calling ic_addba_request to permit drivers
to override when they handle seq# generation (e.g. mwl)
control over the result of buildworld and installworld; this especially
helps packaging systems such as nanobsd

Because pseudo-terminal master file descriptors no longer have a vnode
underneath, we have to fill in fstat() values ourselves. Make our
implementation somewhat sane by returning the timestamps of the TTY
device node that corresponds with our file descriptor.

the code to prevent useless waste of space.
- Remove support for quote bits. There is not a single driver that needs
these bits anymore. This means putc() now accepts a char instead of an
int.
- Remove the unneeded catq() and nextc() routines. They were only used
by the old TTY layer.
- Convert the clist code to use ANSI C prototypes.
In the MPSAFE TTY branch I noticed the vfs timestamps inside devfs were
allocated with 0, where the getattr() routine bumps the timestamps to
boottime if the value is below 3600. The reason why it has been designed
like this, is because timestamps during boot are likely to be invalid.
This means that device nodes that are created on demand (posix_openpt())
have timestamps with a value of boottime, which is not what we want.
Solve this by calling vfs_timestamp() inside devfs_alloc().
