remove IBSS and HostAP support from net80211 and 802.11 drivers.
it can be used to shrink RAMDISK kernels for instance (like what
was done for wi(4)).
it also has the benefit of highlighting what is specific to IBSS
and HostAP modes in the code.
the cost is that we now have two code paths to maintain.

when acting as an access point instead of having each driver doing the
job.
tested by krw@ (ral AP) and me with several drivers.

From Andrew Thompson at FreeBSD.

pass a pointer to an ieee80211_rxinfo structure containing those two
fields plus an extra flags field that indicates whether the frame was
decrypted by hardware or not.
required for a future fix.

handshake protocols (both supplicant and authenticator state
machines) as defined in the IEEE 802.11i standard.
Software implementation of the TKIP (Temporal Key Integrity
Protocol) and CCMP (CTR with CBC-MAC Protocol) protocols.
This diff doesn't implement any of the 802.1X authentication
protocols and thus only PSK authentication (using pre-shared
keys) is currently supported.
In concrete terms, this adds support for WPA-PSK and WPA2-PSK
protocols, both in station and hostap modes.
The following drivers are marked as WPA-capable and should
work: bwi(4), malo(4), ral(4), iwn(4), wpi(4), ural(4),
rum(4), upgt(4), and zyd(4)
The following options have been added to ifconfig(8):
wpa, wpapsk, wpaprotos, wpaakms, wpaciphers, wpagroupcipher
wpa-psk(8) can be used to generate keys from passphrases.
tested by many@

so that it shows up before the :. as a result, all the usb devices do not
need to have name printing code anymore. all this now works and prints
nicely because usbd_probe_and_attach() is serialized. ok kettenis

(This might look easy, but it was a big diff. Thanks to dlg and especially jsg
for looking over it; we found at least four mistakes in the initial diff.)

and it was not consistently used. It was confusing as it suggested these
functions were static, which they were not.
discussed with dlg and jsg, ok jsg.

static mbuf results in a mbuf tag memory leak. Same change as in rum(4).

i removed it in my last commit because i thought it was gone.
looks like it's not the case.

- use the newly introduced ieee80211_get_rts() and
ieee80211_get_cts_to_self() functions.
- use CTS-to-self instead of RTS/CTS to protect OFDM frames in
a mixed 11b/g BSS.
- make sure multicast frames are sent using CCK modulation.
remove support for 5GHz radios in ral(4) RT2560 and ural(4).
i'm not aware of any such adapters on the market and 11a code
is known to be broken.
some cleanup while i'm here.

redefining ic->ic_newassoc.
this should prevent "bogus xmit rate" panics when operating in HostAP
mode.
|

use IFQ_POLL()/IFQ_DEQUEUE() logic instead as described in altq(4).

MCLBYTES (usually 2048).
allocate tx xfer buffers of IEEE80211_MTU_MAX instead of MCLBYTES.
rx buffers are still limited to MCLBYTES though.

- in ral_newstate(), save the "arg" parameter so we can pass it to the
ieee80211_newstate() function in the usb task

Now I can see probes cycling 1->14 instead of just
sitting at channel 1.

don't try to release references to nodes that have been freed by net80211.
in HostAP mode, when switching to the INIT state, net80211 sends a DISASSOC
and a DEAUTH frame to all associated stations and immediately free all the
nodes while we may still hold references to them in our Tx queues.

ieee80211_input() do the job.
