|
* 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.

* 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
|
|

|
|
* 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

|
|

|
|
* for ALLMULTI must go into PROMISC and filter unicast packets
|
|
* mcast code resurrection
|
|
* 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
|
|

|
|
* error handling of ECF command completions
|

|
|
* _reset - check where needed
|
|
* splimp or splnet?
|

|
|
* spinning in ray_cmd_issue
|
