rt2x00: Add kill_tx_queue callback function

2009-02-09T20:03:34+00:00

provide rt2x00lib the possibility to kill a particular TX queue.
This can be useful when disabling the radio, but more importantly
will allow beaconing to be disabled when mac80211 requests this
(during scanning for example)

rt2x00: Remove ENTRY_TXD_OFDM_RATE

2009-01-29T20:58:40+00:00

The flag ENTRY_TXD_OFDM_RATE isn't flexible enough
to indicate which rate modulation should be used for
a frame. This will become a problem when 11n support
is added.

Remove the flag and replace it with an enum value which
can better indicate the exact rate modulation.

rt2x00: Move code into seperate functions

2009-01-29T20:58:39+00:00

Some functions have grown rapidly in size over the last time,
some of those functions (like the rt2x00queue_create_tx_descriptor)
will further increase in size soon, so it is best to start cutting
it into logical pieces.

rt2x00: Rename CONFIG_CRYPTO_COPY_IV

2009-01-29T20:58:37+00:00

CONFIG_CRYPTO_COPY_IV is a bad name since it is part
of the driver requirements instead of a configuration option.

rt2x00: Fix TX rate short preamble detection

2009-01-22T18:55:01+00:00

Mac80211 provides 2 structures to handle bitrates, namely
ieee80211_rate and ieee80211_tx_rate. To determine the short preamble
mode for an outgoing frame, the flag IEEE80211_TX_RC_USE_SHORT_PREAMBLE
must be checked on ieee80211_tx_rate and not ieee80211_rate (which rt2x00 did).

This fixes a regression which was triggered in 2.6.29-rcX as reported by Chris Clayton.

rt2x00: Fix TX short preamble detection

2009-01-12T19:24:50+00:00

The short preamble mode was not correctly detected during TX,
rt2x00 used the rate->hw_value_short field but mac80211 is not
using this field that way.
Instead the flag IEEE80211_TX_RC_USE_SHORT_PREAMBLE should be
used to determine if the frame should be send out using
short preamble or not.

rt2x00: Move crypto TX descriptor handling to rt2x00crypto.c

2008-12-05T14:35:57+00:00

Move all code which determines the right TX descriptor
fields specific to crypto support into rt2x00crypto.c.
This makes the code in rt2x00queue more simpler and
better concentrates all crypto code into a single location.

With this we can also remove some ifdefs in rt2x00queue.c
since the code inside the ifdef is either very small, or
only calling empty functions (see empty function definitions
in rt2x00lib.h).

rt2x00: Implement HW encryption (rt2500usb)

rt2500usb supports hardware encryption.
rt2500usb supports up to 4 shared and pairwise keys.

rt2x00: Store retry limit values

2008-12-05T14:35:50+00:00

Store retry limit values in the rt2x00dev structure.
This allows the removal of the FIXME where we assumed
the long retry is only used when working with RTS frames.

Instead we should check the current retry limit values
and decide if the required retry count for this frame
is a long or short retry.
