ae72afe0f2 The kernel implemented 'memcmp' is an alias for 'bcmp'. However, memcmp
and bcmp are not the same thing.  'man bcmp' states that the return is
"non-zero" if the two byte strings are not identical.  Where as,
'man memcmp' states that the return is the "difference between the
first two differing bytes (treated as unsigned char values" if the
two byte strings are not identical.

So provide a proper memcmp(9), but it is a C implementation not a tuned
assembly implementation.  Therefore bcmp(9) should be preferred over memcmp(9).

a1215e37a4 Introduce a hooks layer for the MPSAFE TTY layer.
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.

d344ffe549 Fix style(9) issue in TTY header files: document function argument names.
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 *'.

30105b9cc7 Make the make_pseudo_driver.sh shellscript work again.
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.

4a0a13971e When invoking the udp_send() from udp6_send() due to use of a v6-mapped
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.

fdabd982e7 Revamp ht ie handling:
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.

01a03542b1 Add current transmit parameters for fixed rate handling so drivers
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.

e6e547d57b Crypto api changes:
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)

45f856e3ac Cleanup AMPDU handling:
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)
