*
* 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.
*
* So, if you want to use this driver make sure that
* options RAY_NEED_CM_FIXUP
* options RAY_NEED_CM_REMAPPING
* are in your kernel configuration file.
*
* 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 translation/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 translation. 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 translations
* 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.

/*
* 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
*
* ***stop/unload needs to drain comq
* ***stop/unload 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
* ***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?
* why can't download use sc_promisc?
* macro for gone and check is at head of all externally called routines
* for ALLMULTI must go into PROMISC and filter unicast packets
* mcast code resurrection
* softc and ifp in variable definition block
* UPDATE_PARAMS seems to return 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
* probably function/macro to test unload at top of commands
* proper setting of mib_hop_seq_len with country code for v4 firmware
* _reset - check where needed
* splimp or splnet?
* more translations
* tidy #includes - we cant need all of these
* infrastructure mode
* needs handling of basic rate set
* all ray_sj, ray_assoc sequencues need a "nicer" solution as we
* need to consider WEP
* acting as ap - should be able to get working from the manual
* differeniate between parameters set in attach and init
* spinning in ray_cmd_issue
* make RAY_DEBUG a knob somehow - either sysctl or IFF_DEBUG
* callout handles need rationalising. can probably remove sj_timerh
* fragmentation when rx level drops?
* proper handling of the basic rate set - see the manual

* 2) That the IFF_OACTIVE flag is checked before this code is called
* (i.e. that the output part of the interface is idle)
*
* A simple one packet at a time TX routine is used - we don't bother
* chaining TX buffers. Performance is sufficient to max out the
* 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.
*
* Nonname box old+FreeBSD-3.4 (K6-233MHz) to
* Libretto 50CT new+FreeBSD-3.1 (75MHz Pentium) 110.77kB/s
* AST J30 Windows 95A (100MHz Pentium) 109.40kB/s
*
* AST J30 Windows 95A (100MHz Pentium) to

*
* Given that 160kB/s is saturating the 2Mb/s wireless link we
* are about there.
*
* There is a little test in the code to see how many packets
* could be chained together. For the FTP test this rarely showed
* any and when it did, only two packets were on the queue.
*
