freebsd-nq/sys/dev/ray/if_ray.c
Duncan Barclay bd0f7bd72d Added reset code and converted many panics into call to reset. 
Finished ray_stop and ray_unload.

A little more macro tidying.

*
* 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.

* i think i've got all the places to set it right, but not so sure

* shutdown
* promisoius

netbsd
driver uses a loop
repeat
get a ccs
get a mbuf
translate and send packet to shared ram
until (no more ccs's) || (no more mbuf's)
send ccs chain to card
exit
Linux
driver is simple single shot packet (with a lot of spinlocks!)
general
the tx space is 0x7000 = 28kB, and TX buffer size is 2048 so there
can be 14 requests at 2kB each
from this 2k we have to remove the TIB - whatever that is - for data
netbsd:
we need to call _start after receiveing a packet to see
if any packets were queued whilst in the interrupt
there is a potential race in obtaining ccss for the tx, in that
we might be in _start synchronously and then an rx interrupt
occurs. the rx will call _start and steal tx ccs from underneath
the interrupted entry.
toptions
dont call _start from rx interrupt
find a safe way of locking
find a better way of obtaining ccs using next free avilable?
look at other drivers
use tsleep/wakeup
some form of ring to hold ccs
free lsit
rework calling
