2011-08-24mac80211: mesh gate implementationJavier Cardona6-9/+335
In this implementation, a mesh gate is a root node with a certain bit set in its RANN flags. The mpath to this root node is marked as a path to a gate, and added to our list of known gates for this if_mesh. Once a path discovery process fails, we forward the unresolved frames to a known gate. Thanks to Luis Rodriguez for refactoring and bug fix help.

2011-08-22mwl8k: Traffic to clients gets affected when one client leaves a cyrpto bssNishant Sarmukadam1-3/+0
When a client disassociates from a crypto enabled bss, data traffic to other clients connected to the bss is stalled. This was due to a boolean variable used to keep track if HW crypto is enabled i.e. if set key has been called to add a key. This flag was being reset every time delete key was called e.g when a station leaves the bss. Once the flag is reset, rx status flags were not being set for connected clients which disrupts traffic to these clients. Fix this issue by not resetting the flag since we do not need to reset this flag during the life time of the bss. Signed-off-by: Nishant Sarmukadam <nishants@marvell.com> Signed-off-by: John W.

2011-08-22mac80211: Tear down BA session on BAR tx failureHelmut Schaa1-0/+18
As described at [1] some STAs (i.e. Intel 5100 Windows) can end up correctly BlockAcking incoming frames without delivering them to user space if a AMPDU subframe got lost and we don't flush the receipients reorder buffer with a BlockAckReq. This in turn results in stuck connections. According to 802.11n-2009 it is not necessary to send a BAR to flush the recepients RX reorder buffer but we still do that to be polite. However, assume the following frame exchange: AP -> STA, AMPDU (failed) AP -> STA, BAR (failed) The client in question then ends up in the same situation and won't deliver frames to userspace anymore since we weren't able to flush its reorder buffer. This is not a hypothetical situation but I was able to observe this exact behavior during a stress test between a rt2800pci AP and a Intel 5100 Windows client. In order to work around this issue just tear down the BA session as soon as a BAR failed to be TX'ed.

b43_op_config and b43_op_bss_info_changed apply many settings by directly writing to hardware registers. These settings are lost as soon as the core is restarted and the initvals are reloaded.

2011-08-12ath9k: remove eeprom txgain override for minor version < 19Marek Lindner1-4/+1
ath9k_hw_4k_get_eeprom() overrides the eeprom value for txgain if the minor version is not 19 or above with a value of 0. ar9002_hw_init_mode_gain_regs() relies on this information to determine whether this is a high power wifi card or not. The override caused the driver to always use the 'normal' power tables even for high power devices if their minor version was not high enough. Thus leading to reduced power output. This isn't needed for the AR9285; the check originated with the AR9280 setup code which requires the EEPROM version check.

When a PREQ or PREP is received from an intermediate node, it contains useful information for path selection but it doesn't include the originator's sequence number. Therefore, when updating the mesh path to that intermediate node, we should not set the MESH_PATH_SN_VALID flag.
