When the system is resumed a deadlock can occur when DPC gets entered before resume is complete. This patch fixes this by properly checking the suspend state outside the claim_host code block. Reviewed-by:

On every tx the flow worker is triggered. When running high throughput data this causes an excessive amount of times the worker gets activated. This patch starts scheduling the worker more relaxed once outstanding tx has reached a certain depth. Reviewed-by:

Tuning rings size for performance optimization. Increasing Tx ring size, allows buffering more packets for HW, thus eliminating idle periods which were observed with smaller ring at high throughput, because HW was fetching packets faster than driver was filling them into the TX ring. Rx ring was similarly increased to avoid same problems in Rx. Signed-off-by:

upon cfg80211_stop_ap, a graceful AP shutdown is requested from firmware followed by firmware reset. In case graceful request failed, error was returned to cfg80211. The change is to return success in this scenario, because firmware reset will anyhow shutdown the AP. Signed-off-by:

netif_carrier_on indication was too late. In case Rx packet received before netif_carrier_on indication, upper layers could not send Tx packet back. The fix is to indicate netif_carrier_on earlier: for STA, indicate netif_carrier_on when association starts. for AP/PCP, indicate netif_carrier_on upon starting AP/PCP. Signed-off-by:

Some devices do not support extended scan. This patch adds support to enble ext_scan selectively. For SD/PCIe interfaces, deefine ext_scan_support as part of card structure and use it to initialize ext_scan in adapter during registering device. For USB interfaces, we initialize ext_scan during register_dev handler. Signed-off-by:

ath9k and ath9k_htc use the variable name "led_blink" to indicate whether the module parameter "blink" is on. This name is easy to conflict with other variables, and has caused a compiler error found by kbuild test bot.

The kernel's string library does in fact have strcasecmp, at least since ded220bd ("[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.

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.

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(). Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:
