49c1d2085b Move orinoco Kconfig entries into drivers/net/wireless/orinoco/Kconfig
Since driver now lives in separate subdirectory, move Kconfig entries
in own file so they can be tweaked indepndently. It complements
"orinoco: Move sources to a subdirectory".

47166791b7 orinoco: Remove unused variable rx_data
Probably something leftover from experimentation with tasklets. Now the
structure declaration orinoco_rx_data can be relocated to orinoco.c

9ee677c227 wireless: Add channel/frequency conversions to ieee80211.h
Added mappings for FHSS, DSSS and OFDM channels - with macros to point
HR DSSS and ERP to the DSSS mappings. Currently just static inline
functions.

Use the new functions in the older fullmac drivers. This eliminates a
number of const static buffers and removes a couple of range checks that
are now redundant.

11eaea4167 orinoco: use KERN_DEBUG for link status messages
KERN_INFO is too "loud" for messages that are generated by the ordinary
events, such as accociation.  Use of KERN_DEBUG is consistent with
mac80211.

20953ad68e orinoco: take the driver lock in the rx tasklet
Fix the warning reproduced below.

We add to rx_list in interrupt context and remove elements in tasklet
context. While removing elements we need to prevent the interrupt
modifying the list.

Note that "orinoco: Process bulk of receive interrupt in a tasklet" did not
preserve locking semantics on what is now orinoco_rx.

This patch reinstates the locking semantics and ensures it covers
rx_list as well. This leads to additional cleanup required in
free_orinocodev.

39d1ffee57 orinoco: Provide option to avoid unnecessary fw caching
Make firmware caching on startup optional, and make it default.

When the option is not selected and PM_SLEEP is configured, then
cache firmware in the suspend pm_notifier. This configuration saves
about 64k RAM in normal use, but can lead to a situation where the
driver is configured to use a different firmware.
