70 * This card is unusual in that it uses both common and attribute
71 * memory whilst working. The -stable versions of FreeBSD have a real
72 * problem managing and setting up the correct memory maps. This
73 * driver should reset the memory maps correctly under PAO and non-PAO
74 * -stable systems. Work is in hand to fix these problems for -current.
76 * So, if you want to use this driver make sure that
77 * options RAY_NEED_CM_FIXUP
78 * options RAY_NEED_CM_REMAPPING
79 * are in your kernel configuration file.
81 * The first fixes the brain deadness of pccardd (where it reads the
82 * CIS for common memory, sets it all up and then throws it all away
83 * assuming the card is an ed driver...). Note that this could be
84 * dangerous (because it doesn't interact with pccardd) if you
85 * use other memory mapped cards at the same time.
87 * The second option ensures that common memory is remapped whenever
88 * we are going to access it (we can't just do it once, as something
89 * like pccardd may have read the attribute memory and pccard.c
90 * doesn't re-map the last active window - it remaps the last
91 * non-active window...).
94 * Ad-hoc and infra-structure modes
95 * ================================
97 * At present only the ad-hoc mode is being worked on.
99 * Apart from just writing the code for infrastructure mode I have a
100 * few concerns about both the Linux and NetBSD drivers in this area.
101 * They don't seem to differentiate between the MAC address of the AP
102 * and the BSS_ID of the network. I presume this is handled when
103 * joining a managed n/w and the network parameters are updated, but
104 * I'm not sure. How does this interact with ARP? For mobility we want
105 * to be able to move around without worrying about which AP we are
106 * actually talking to - we should always talk to the BSS_ID.
108 * The Linux driver also seems to have the capability to act as an AP.
109 * I wonder what facilities the "AP" can provide within a driver? We can
110 * probably use the BRIDGE code to form an ESS but I don't think
111 * power saving etc. is easy.
114 * Packet translation/encapsulation
115 * ================================
117 * Currently we only support the Webgear encapsulation
118 * 802.11 header <net/if_ieee80211.h>struct ieee80211_header
119 * 802.3 header <net/ethernet.h>struct ether_header
123 * We should support whatever packet types the following drivers have
124 * if_wi.c FreeBSD, RFC1042
125 * if_ray.c NetBSD Webgear, RFC1042
126 * rayctl.c Linux Webgear, RFC1042
127 * also whatever we can divine from the NDC Access points and Kanda's boxes.
129 * Most drivers appear to have a RFC1042 translation. The incoming packet is
130 * 802.11 header <net/if_ieee80211.h>struct ieee80211_header
134 * This is translated to
135 * 802.3 header <net/ethernet.h>struct ether_header
139 * Linux seems to look at the SNAP org_code and do some translations
140 * for IPX and APPLEARP on that. This just may be how Linux does IPX
141 * and NETATALK. Need to see how FreeBSD does these.
143 * Translation should be selected via if_media stuff or link types.
149 * _stop - mostly done
150 * would be nice to understand shutdown/or power save to prevent RX
152 * just needs calling in the right places
153 * converted panics to resets - when tx packets are the wrong length
154 * may be needed in a couple of other places when I do more commands
155 * havenet - mostly done
156 * i think i've got all the places to set it right, but not so sure
157 * we reset it in all the right places
159 * recreated most of stop but as card is unplugged don't try and
160 * access it to turn it off
163 * I would much prefer to have the complete 802.11 packet dropped to
164 * the bpf tap and then have a user land program parse the headers
165 * as needed. This way, tcpdump -w can be used to grab the raw data. If
166 * needed the 802.11 aware program can "translate" the .11 to ethernet
168 * use std timeout code for download - done
169 * was mainly moving a call and removing a load of stuff in
170 * download_done as it duplicates check_ccs and ccs_done
172 * add the start_join_net - done
174 * remove startccs and startcmd - done
175 * as those were used for the NetBSD start timeout
176 * multicast - done but UNTESTED
177 * I don't have the ability/facilty to test this
179 * stats reported via raycontrol
180 * getparams ioctl - done
181 * reported via raycontrol
182 * start_join_done needs a restart in download_done - done
183 * now use netbsd style start up
186 * translation, BSS_ID, countrycode, changing mode
190 * _reset - check where needed
194 * infrastructure mode - maybe need some of the old stuff for checking?
195 * differeniate between parameters set in attach and init
196 * spinning in ray_issue_cmd
197 * fix the XXX code in start_join_done
198 * make RAY_DEBUG a knob somehow - either sysctl or IFF_DEBUG
199 * ray_update_params_done needs work
200 * do an rx level and antenna cache, the antenna can be used to set c_antenna
202 * callout handles need rationalising. can probably remove timerh and
203 * use ccs_timerh for download and sj_timerh
