Removed NETBSDTX spares. Renamed a load of functions - specifcally start -> tx init has download, sj and assoc as sub-functions report_params and update params move to repparams/upparams Tidied up old #define's Got rid of old DPRINTF, made printf's RAY_PRINTF and panic's RAY_PANIC All code KNF Removed checking the ECF_TO_HOST area in ray_init - this gets hosed when someone updates/read a parameter from the card so causes unneeded grief. This required moving the tib check into ray_attach. Changed handling of interface flags in ioctl so that promiscous mode changes are only done as needed. Sequences of comq entries can be added to an array and automatically dealt with - used in ray_init_user and others. Moved IFF_RUNNING checks from the comq commands to com_runq - still not sure what to do so we PANIC - will be fixed. ray_sj now checks to see if any of the parameters it can update can be updated. ray_sj_done now updates parameters to the current n/w set if we changed them earlier. I was being a bit thick in earlier comments as to why this check was done - the ECF never changes the parameters. Assocication with APs is handled outside of ray_sj - need to add WEP stuff if I ever get my hands on an AP. ray_stop, ray_unload and ray_reset are currently broken - reset isn't used anyway. ray_tx_XXX and ray_rx only have cosmetic changes. Interrupt handler now gets command out of ccs. This is so ray_intr_ccs and ray_intr_rcs don't need to remap CM (I'm trying to roll things up a bit as it must be slowing us down). ray_intr_ccs just vectors commands to functions or error checks - a jump table could replace it in ray_intr. Ditto for ray_intr_rcs. mcast is currently broken - I need to do more work for ALLMULTI etc. This is reasonably easy to fix becuase of the comq array stuff. Added a few more checks into repparams so that it is firmware version aware. It also uses the new comq framework. Parameter updating is also much better with the update parameter return routine re-worked. Added a couple of runq entry helper functions - one that malloc's a new entry and fills it in with sensible defaults and another that adds and runs a seqencue of entries.

|
* 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.
