rt2x00: Implement support for 802.11n

2009-05-06T19:14:50+00:00

Extend rt2x00lib capabilities to support 802.11n,
it still lacks aggregation support, but that can
be added in the future.

rt2x00: Add support for L2 padding during TX/RX

2009-05-06T19:14:49+00:00

Some hardware require L2 padding between header and payload
because both must be aligned to a 4-byte boundary. This hardware
also is easier during the RX path since we no longer need to
move the entire payload but rather only the header to remove
the padding (mac80211 only wants the payload to be 4-byte aligned).

rt2x00: Move iv_len into tx descriptor data

2009-05-06T19:14:49+00:00

By placing the iv_len into the tx descriptor data and
by passing this data to the crypto IV handlers we can
save multiple calls to ieee80211_get_hdrlen_from_skb()
and some if-statements when copying/removing the IV data
from the outgoing frame.

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.
