70 * This card is unusual in that it uses both common and attribute
71 * memory whilst working. It should use common memory and an IO port.
73 * The bus resource allocations need to work around the brain deadness
74 * of pccardd (where it reads the CIS for common memory, sets it all
75 * up and then throws it all away assuming the card is an ed
76 * driver...). Note that this could be dangerous (because it doesn't
77 * interact with pccardd) if you use other memory mapped cards in the
78 * same pccard slot as currently old mappings are not cleaned up very well
79 * by the bus_release_resource methods or pccardd.
81 * There is no support for running this driver on 4.0.
83 * Ad-hoc and infra-structure modes
84 * ================================
86 * The driver supports ad-hoc mode for V4 firmware and infrastructure
87 * mode for V5 firmware. V5 firmware in ad-hoc mode is untested and should
90 * The Linux driver also seems to have the capability to act as an AP.
91 * I wonder what facilities the "AP" can provide within a driver? We can
92 * probably use the BRIDGE code to form an ESS but I don't think
93 * power saving etc. is easy.
96 * Packet framing/encapsulation/translation
97 * ========================================
99 * Currently we support the Webgear encapsulation:
100 * 802.11 header <net/if_ieee80211.h>struct ieee80211_frame
101 * 802.3 header <net/ethernet.h>struct ether_header
104 * and RFC1042 encapsulation of IP datagrams (translation):
105 * 802.11 header <net/if_ieee80211.h>struct ieee80211_frame
111 * Framing should be selected via if_media stuff or link types but
112 * is currently hardcoded to:
120 * 802.11 provides two authentication mechanisms. The first is a very
121 * simple host based mechanism (like xhost) called Open System and the
122 * second is a more complex challenge/response called Shared Key built
125 * This driver only supports Open System and does not implement any
126 * host based control lists. In otherwords authentication is always
127 * granted to hosts wanting to authenticate with this station. This is
128 * the only sensible behaviour as the Open System mechanism uses MAC
129 * addresses to identify hosts. Send me patches if you need it!
133 * ***check all XXX_INFRA code - reassoc not done well at all!
134 * ***watchdog to catch screwed up removals?
135 * ***error handling of RAY_COM_RUNQ
136 * ***error handling of ECF command completions
137 * ***can't seem to create a n/w that Win95 wants to see.
138 * ***remove panic in ray_com_ecf by re-quing or timeout
139 * ***use new ioctl stuff - probably need to change RAY_COM_FCHKRUNNING things?
140 * consider user doing:
141 * ifconfig ray0 192.168.200.38 -bssid "freed"
142 * ifconfig ray0 192.168.200.38 -bssid "fred"
143 * here the second one would be missed in this code
144 * check that v5 needs timeouts on ecf commands
145 * write up driver structure in comments above
146 * UPDATE_PARAMS seems to return via an interrupt - maybe the timeout
147 * is needed for wrong values?
148 * proper setting of mib_hop_seq_len with country code for v4 firmware
149 * best done with raycontrol?
150 * countrycode setting is broken I think
151 * userupdate should trap and do via startjoin etc.
152 * fragmentation when rx level drops?
153 * v5 might not need download
154 * defaults are as documented apart from hop_seq_length
155 * settings are sane for ad-hoc not infra
158 * most state is implied by the sequence of commands in the runq
159 * but in fact any of the rx and tx path that uses variables
160 * in the sc_c are potentially going to get screwed?
163 * proper handling of the basic rate set - see the manual
164 * all ray_sj, ray_assoc sequencues need a "nicer" solution as we
165 * remember association and authentication
166 * need to consider WEP
167 * acting as ap - should be able to get working from the manual
168 * need to finish RAY_ECMD_REJOIN_DONE
169 * finish authenitcation code, it doesn't handle errors/timeouts/
173 * promisc in here too? - done
174 * should be able to update the parameters before we download to the
175 * device. This means we must attach a desired struct to the
176 * runq entry and maybe have another big case statement to
177 * move these desired into current when not running.
178 * init must then use the current settings (pre-loaded
179 * in attach now!) and pass to download. But we can't access
180 * current nw params outside of the runq - ahhh
181 * differeniate between parameters set in attach and init
182 * sc_station_addr in here too (for changing mac address)
183 * move desired into the command structure?
184 * take downloaded MIB from a complete nw_param?
185 * longer term need to attach a desired nw params to the runq entry
