General tidy up and plough through TODO list.
Rewrote intro at top of file to reflect my better understanding of how it the memory mapping works. Clear the DONE list and move some thoughts into the TODO list. Remove RECERR from RAY_DEBUG Start to use a desired network parameter structure, only used in download code as I've realised that there are some problems with the idea. Break up ray_rx, and move the data packet handler into a seperate function. This meant some knock on changes in ray_rx_mgt/ray_rx_ctl to do with mbuf freeing. Remove some debug code/XXX comments that are out of date.

|
||||
* 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.
|
||||
* memory whilst working. It should use common memory and an IO port.
|
||||
*
|
||||
* 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 3.x branch of FreeBSD has a real problem managing and setting
|
||||
* up the correct memory maps. However, this driver should reset the
|
||||
* memory maps correctly - it works around for 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...).
|
||||
* There is no support for running this driver on 4.0.
|
||||
*
|
||||
* For >4.1 and -cuurent things are a lot better.
|
||||
*
|
||||
* 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.
|
||||
* I hope to start work on support for infrastructure when an AP arrives
|
||||
* from FreeBSD Labs.
|
||||
*
|
||||
* 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
