PATCH 1/6 rt2x00: Antenna diversity does not work in 2.6.35

From: Lars Ericsson <[email protected]>

The test if antenna diversity is at all enabled uses a local variable 'flags' to prepare the test condition, but uses 'ant->flags' when the test is evaluated. The effect is that the diversity evaluation will never start. I can see two solutions, use the 'flag' in the test condition or revert the local flag change. My attached patch took alternative two.

Then the evaluation start but it will still not switch antenna. The problem is a code section in rt2x00lib_config_antenna (). The effect of that code section is that any change the diversity function perform will be effectively shorten and no antenna selection command issued. The attached patch will filter out any ANTENNA_SW_DIVERSITY setting but forward all other

PATCH 2/6 rt2x00: Initialize AMPDU_BA_WINSIZE register

From: Helmut Schaa <[email protected]>

Since we're not using the AMPDU_BA_WINSIZE register to force the BlockAck window size (we specify it in every TXWI) we should initialize it to 0.

PATCH 3/6 rt2x00: Check for specific changed flags when updating the erp config

From: Helmut Schaa <[email protected]>

Previously rt2x00 was always updating all erp related config variables even though mac80211 might only have changed one. Hence, pass the changed flags to the config_erp driver callback so that the driver can limit the changes to the correct values.

This fixes an issue in AP mode where the beacon interval is not initialized (and thus zero) but still sent to the hardware causing an interrupt storm on rt2800pci hanging the system.

PATCH 4/6 rt2x00: Mask out unused interrupts in rt2800pci

From: Helmut Schaa <[email protected]>

We don't use all available interrupts in rt2800pci. Mask out all unused interrupts to avoid waking up without having anything to do.

PATCH 5/6 rt2x00: Enable missing interrupts in rt61pci

From: Helmut Schaa <[email protected]>

We're handling both, the CSR_BEACON_DONE and the CSR_TWAKEUP interrupts in rt61pci. However, these interrupts are masked out by default. Fix this.

Found via pure code inspection.
