1 as the only valid value - so we consider zero to be unset - to save
adding a boolean to the socket structure.

15 years agoath9k: Add data structure for supporting virtual radio/wiphy operation
Jouni Malinen [Tue, 3 Mar 2009 17:23:28 +0000 (19:23 +0200)]
ath9k: Add data structure for supporting virtual radio/wiphy operation

This is the initial step in allowing ath9k to register multiple
virtual radios (wiphys). The goal of virtual radios is to allow the
same radio to be shared for multiple virtual interfaces that may
operate on different channels. The mac80211 virtual interface support
is designed only for single channel operation and as such, it is not
suitable for this type of use. Anyway, it can be used on top of the
virtual radio concept, if desired (e.g., use two virtual radios to
handle two channels and then add multiple mac80211 virtual interfaces
on top of each virtual radio).

The new struct ath_wiphy is now registered as the driver data
structure for wiphy. This structure has a pointer to the shared (among
virtual wiphys of the same physical radio) struct ath_softc data. The
primary wiphy maintains the allocated memory for ath_softc. Secondary
(virtual) wiphys will only allocate the new ath_wiphy structure.

Registration of secondary wiphys is added in a separate patch.

15 years agort2x00: Export all register stats through debugfs

rt2x00: Export all register stats through debugfs

By exporting the register base, and word size to userspace
through debugfs it will be easier to create scripts which
parse the register information. This makes debugging and
register dumps information easier.

This will break my previous scripts which dumped and parsed
all information, but since this is only for debugging purposes
this change should not be a problem.

Dumpfiles created with the old version can be easily manually
edited to make them compatible with this new approach, which
means there will be no problems comparing dumps from the
different versions either.

Also be more consistent with using tabs to seperate different
fields.
