dmlb 27d4800d2f Moved a bit of resource allocation from probe to attach based on feedback 
in -hackers on the correct driver structure.

Started to tidy up _detach and _stop.

Added the comq array stuff into mcast.

*
* Card configuration
* ==================
*
* This card is unusual in that it uses both common and attribute
* memory whilst working. The -stable versions of FreeBSD have a real
* problem managing and setting up the correct memory maps. This
* driver should reset the memory maps correctly under PAO and non-PAO
* -stable systems. Work is in hand to fix these problems for -current.
*
* The first fixes the brain deadness of pccardd (where it reads the
* CIS for common memory, sets it all up and then throws it all away
* assuming the card is an ed driver...). Note that this could be
* dangerous (because it doesn't interact with pccardd) if you
* use other memory mapped cards at the same time.
*
* The second option ensures that common memory is remapped whenever
* we are going to access it (we can't just do it once, as something
* like pccardd may have read the attribute memory and pccard.c
* doesn't re-map the last active window - it remaps the last
* non-active window...).
*
*
* Ad-hoc and infra-structure modes
* ================================
*
* At present only the ad-hoc mode is being worked on.
*
* Apart from just writing the code for infrastructure mode I have a
* few concerns about both the Linux and NetBSD drivers in this area.
* They don't seem to differentiate between the MAC address of the AP
* and the BSS_ID of the network. I presume this is handled when
* joining a managed n/w and the network parameters are updated, but
* I'm not sure. How does this interact with ARP? For mobility we want
* to be able to move around without worrying about which AP we are
* actually talking to - we should always talk to the BSS_ID.
*
* The Linux driver also seems to have the capability to act as an AP.
* I wonder what facilities the "AP" can provide within a driver? We can
* probably use the BRIDGE code to form an ESS but I don't think
* power saving etc. is easy.
*
*
* Packet framing/encapsulation
* ================================
*
* Currently we only support the Webgear encapsulation
* 802.11 header <net/if_ieee80211.h>struct ieee80211_header
* 802.3 header <net/ethernet.h>struct ether_header
* 802.2 LLC header
* 802.2 SNAP header
*
* We should support whatever packet types the following drivers have
* if_wi.c FreeBSD, RFC1042
* if_ray.c NetBSD Webgear, RFC1042
* rayctl.c Linux Webgear, RFC1042
* also whatever we can divine from the NDC Access points and Kanda's boxes.
*
* Most drivers appear to have a RFC1042 framing. The incoming packet is
* 802.11 header <net/if_ieee80211.h>struct ieee80211_header
* 802.2 LLC header
* 802.2 SNAP header
*
* This is translated to
* 802.3 header <net/ethernet.h>struct ether_header
* 802.2 LLC header
* 802.2 SNAP header
*
* Linux seems to look at the SNAP org_code and do some framings
* for IPX and APPLEARP on that. This just may be how Linux does IPX
* and NETATALK. Need to see how FreeBSD does these.
*
* Translation should be selected via if_media stuff or link types.
*
*
* Authentication
* ==============
*
* 802.11 provides two authentication mechanisms. The first is a very
* simple host based mechanism (like xhost) called Open System and the
* second is a more complex challenge/response called Shared Key built
* ontop of WEP.
*
* This driver only supports Open System and does not implement any
* host based control lists. In otherwords authentication is always
* granted to hosts wanting to authenticate with this station. This is
* the only sensible behaviour as the Open System mechanism uses MAC
* addresses to identify hosts. Send me patches if you need it!

/*
* TODO
*
* _stop - mostly done
* would be nice to understand shutdown/or power save to prevent RX
* _reset - done
* just needs calling in the right places
* converted panics to resets - when tx packets are the wrong length
* may be needed in a couple of other places when I do more commands
* havenet - mostly done
* i think i've got all the places to set it right, but not so sure
* we reset it in all the right places
* _unload - done
* recreated most of stop but as card is unplugged don't try and
* access it to turn it off
* TX bpf - done
* RX bpf - done
* I would much prefer to have the complete 802.11 packet dropped to
* the bpf tap and then have a user land program parse the headers
* as needed. This way, tcpdump -w can be used to grab the raw data. If
* needed the 802.11 aware program can "translate" the .11 to ethernet
* for tcpdump -r
* use std timeout code for download - done
* was mainly moving a call and removing a load of stuff in
* download_done as it duplicates check_ccs and ccs_done
* promisoius - done
* add the start_join_net - done
* i needed it anyway
* remove startccs and startcmd - done
* as those were used for the NetBSD start timeout
* multicast - done but UNTESTED
* I don't have the ability/facilty to test this
* rxlevel - done
* stats reported via raycontrol
* getparams ioctl - done
* reported via raycontrol
* start_join_done needs a restart in download_done - done
* now use netbsd style start up
* ioctls - done
* use raycontrol
* translation, BSS_ID, countrycode, changing mode
* ifp->if_hdr length - done
* rx level and antenna cache - done
* antenna not used yet
* antenna tx side - done
* not tested!
* shutdown - done
* the driver seems to do the right thing for plugging and unplugging
* cards
* apm/resume - ignore
* apm+pccard is borken for 3.x - no one knows how to do it anymore
* fix the XXX code in start_join_done - n/a
* i've removed this as the error handling should be consistent for
* all ECF commands and none of the other commands bother!
* ray_update_params_done needs work - done
* as part of scheduler/promisc re-write
* raycontrol to be firmware version aware - done
* also report and update parameters IOCTLs are version aware
* make RAY_DPRINTFN RAY_DPRINTF - done
* make all printfs RAY_PRINTF - done
* faster TX routine - done
* see comments but OACTIVE is gone
* __P to die - done
* the rest is ansi anyway
* macroize the attribute read/write and 3.x driver - done
* like the SRAM macros?
* rename "translation" to framing for consitency with Webgear - done
* severe breakage with CCS allocation - done
* ccs are now allocated in a sleepable context with error recovery
* resource allocation should be be in attach and not probe - done
* resources allocated in probe hould be released before probe exits - done
* softc and ifp in variable definition block - done
* callout handles need rationalising. can probably remove sj_timerh - done
*
* ***stop/detach need to drain comq
* ***stop/detach checks in more routines
* ***reset in ray_init_user?
* ***IFF_RUNNING checks are they really needed?
* ***PCATCH tsleeps and have something that will clean the runq
* ***priorities for each tsleep
* ***watchdog to catch screwed up removals?
* ***check and rationalise CM mappings
* ***should the desired nw parameters move into the comq entry to maintain
* correct sequencing?
* use /sys/net/if_ieee80211.h and update it
* why can't download use sc_promisc?
* macro for gone and check is at head of all externally called routines
* probably function/macro to test unload at top of commands
* for ALLMULTI must go into PROMISC and filter unicast packets
* mcast code resurrection
* UPDATE_PARAMS seems to return via an interrupt - maybe the timeout
* is needed for wrong values?
* remember it must be serialised as it uses the HCF-ECF area
* check all RECERRs and make sure that some are RAY_PRINTF not RAY_DPRINTF
* havenet needs checking again
* error handling of ECF command completions
* proper setting of mib_hop_seq_len with country code for v4 firmware
* _reset - check where needed
* splimp or splnet?
* tidy #includes - we cant need all of these
* differeniate between parameters set in attach and init
* more translations
* spinning in ray_com_ecf
* make RAY_DEBUG a knob somehow - either sysctl or IFF_DEBUG
* fragmentation when rx level drops?
*
* infra mode stuff
* proper handling of the basic rate set - see the manual
* all ray_sj, ray_assoc sequencues need a "nicer" solution as we
* remember association and authentication
* need to consider WEP
* acting as ap - should be able to get working from the manual
*
* ray_nw_param- promisc in here too?
* ray_nw_param- sc_station_addr in here too (for changing mac address)
* ray_nw_param- move desired into the command structure?

*
* A simple one packet at a time TX routine is used - we don't bother

* wireless link on a P75. Earlier versions of this used to set
* OACTIVE to add an extra layer of locking. It isn't really needed.
*
* Removing the OACTIVE gives much better performance. Here we
* have this driver on a Libretto, the old driver (OACTIVE)
* on a K6-233 and the Windows driver on a P100. FTPing 2048k
* of zeros.

* There is a little test in the code to see how many packets
