2022-10-10wifi: mac80211: add wake_tx_queue callback to driversAlexander Wetzel1-0/+1
mac80211 is fully switching over to the internal TX queue (iTXQ) implementation. Update all drivers not yet providing the now mandatory wake_tx_queue() callback. As an side effect the netdev interfaces of all updated drivers will switch to the noqueue qdisc.

This can be reproduced by bind/unbind the driver multiple times in AM3517 board. Analysis revealed that rtl8187_start() was invoked before probe finishes(ie. before the mutex is initialized).

It seems like a historic accident that these return unsigned char *, and in many places that means casts are required, more often than not.

2017-03-08rtl8187: Enable monitor mode to fix multicast receptionNils Holland1-9/+7
The rtl8187 cards don't seem to receive multicast frames, which, among other things, makes them fail to receive RAs in IPv6 networks. The cause seems to be that the RTL818X_RX_CONF_MULTICAST flag doesn't have the desired effect. Fix the issue by setting RTL818X_RX_CONF_MONITOR instead, which puts the card into monitor mode and resolves the problem so that multicast frames are sucessfully passed to the kernel. The existence of the problem and the effectiveness of the solution has originally been confirmed on an 8187B based card with the USB id of 0bda:8197. Subsequent testing by Larry Finger on an 8187L based card, which follows the second (8187, i.e. "non-b") code path in the driver, has confirmed that the fix does not cause any noticeable regresssions there either.

2017-03-06wireless: Set NL80211_EXT_FEATURE_CQM_RSSI_LIST in multiple driversAndrew Zaborowski1-0/+2
Set the NL80211_EXT_FEATURE_CQM_RSSI_LIST wiphy extended feature wholesale in all mac80211-based drivers that do not set the IEEE80211_VIF_BEACON_FILTER flags on their interfaces. mac80211 will be processing supplied RSSI values in ieee80211_rx_mgmt_beacon and will detect when the thresholds set by ieee80211_set_cqm_rssi_range_config are crossed. Remaining (few) drivers need code to enable the firmware to monitor the thresholds. This is mostly only compile-tested.

2016-04-12cfg80211: remove enum ieee80211_bandJohannes Berg1-2/+2
This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it. There's no really good reason to not declare the number of bands in nl80211 though, so do that and remove the cfg80211 one. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2015-10-14rtlwifi: rtl818x: Move drivers into new realtek directoryLarry Finger1-0/+1684
Now that a new mac80211-based driver for Realtek devices has been submitted, it is time to reorganize the directories. Rather than having directories rtlwifi and rtl818x be in drivers/net/wireless/, they will now be in drivers/net/wireless/realtek/. This change simplifies the directory structure, but does not result in any configuration changes that are visable to the user.
