2015-01-23bcma: use standard bus scanning during early registerRafał Miłecki
Starting with kernel 3.19-rc1 early registration of bcma on MIPS is done a bit later, with memory allocator available. This allows us to simplify code by using standard bus scanning method. Signed-off-by: Rafał Miłecki <zajec5@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2015-01-23atmel: Remove open-coded and wrong strcasecmpRasmus Villemoes
The kernel's string library does in fact have strcasecmp, at least since ded220bd8f08 ("[STRING]: Move strcasecmp/strncasecmp to lib/string.c"). Moreover, this open-coded version is in fact wrong: If the strings only differ in their last character, a and b have already been incremented to point to the terminating NUL bytes, so they would wrongly be treated as equal.

2015-01-23wcn36xx: initiate TX BA sessionsBob Copeland
Currently, wcn36xx only asks for a TX BA session if it has already established one for RX. Thus, two wcn36xx devices cannot do a-mpdu between themselves since they both wait for the other to go first. Fix this by starting a BA session after a few QoS data frames have been sent to a STA.

2015-01-23wcn36xx: move set_tx_pdu inside set_tx_data/mgmtBob Copeland
The pdu is part of the buffer descriptor, so it makes sense that one function would fill both. Also, passing the whole skb instead of just the header pointer to the set_tx_data function paves the way for using its fields for ampdu setup inside set_tx_data().

2015-01-23wcn36xx: don't process 'valid' descriptorsBob Copeland

2015-01-23wcn36xx: let device generate qos seq numbersBob Copeland
wcn36xx currently sends an incorrect sequence number into the BA session setup firmware command: it should be saving or updating the ssn in the TX_START ampdu_action callback instead of waiting until TX_OPERATIONAL. However, we can sidestep the issue by letting the hardware generate the sequence numbers for QoS frames, as is done in prima, so do that.

2015-01-23wcn36xx: use !! when assigning int as a booleanBob Copeland
bd->tx_comp is a single bit in a bitfield, so assigning "info->flags & IEEE80211_TX_CTL_REQ_TX_STATUS" only happens to work because TX_STATUS is defined to BIT(0); if it were any other bit this assignment would fail.

2015-01-23wcn36xx: initialize device defaults on startBob Copeland

2015-01-22iwlwifi: mvm: fix rx chains configuration in phy ctxt cmdLiad Kaufman
In the PHY_CTXT command sent to the FW the TX chains were indeed configured by the values of both FW TLVs and of NVM, but the RX chains were left out and configured only by FW TLV. This causes problems in 4165 HW, where there are 1x1 antennas, and the wrong configuration denies the driver from connecting to the AP.
