2020-01-16staging: wfx: drop wvif->dtim_periodJérôme Pouiller2-17/+4
It is not necessary to keep a copy of dtim_period in wfx_vif. Prefer to just rely on bss_conf->dtim_period.

2020-01-16staging: wfx: simplify update of DTIM periodJérôme Pouiller3-29/+6
Current code parse the TIM and retrieve the DTIM period. It is far easier to rely on bss_info_changed() for this job. It is no more necessary to run task asynchronously. So set_beacon_wakeup_period_work is now useless.

2020-01-16staging: wfx: simplify wfx_flush()Jérôme Pouiller1-11/+1
Current code of wfx_flush() force to drop packets in some contexts. However, there is no obvious reasons to do that. It looks like a workaround for a bug with the old implementation of __wfx_flush().

2020-01-16staging: wfx: fix __wfx_flush() when drop == falseJérôme Pouiller2-33/+11
wfx_tx_queues_clear() only clear not yet sent requests. So, it always necessary to wait for tx_queue_stats.wait_link_id_empty whatever the value of "drop" argument. In add, it is not necessary to return with tx queue locked since all calls to __wfx_flush() unlock the tx queue just after the call to __wfx_tx_flush().

mac80211 and the device are both able to control tx power per vif. But, the current code retrieve tx power from wfx_config(). So, it does not allow to setup the tx power independently for each vif.

2020-01-16staging: wfx: use specialized structs for HIF argumentsJérôme Pouiller2-11/+20

2020-01-16staging: wfx: send rate policies one by oneJérôme Pouiller1-28/+25
Rate policies (aka. tx_rate_retry_policy in hardware API) are sent to device asynchronously from tx requests. So, the device maintains a list of active rate policies and the tx requests only reference an existent rate policy. The device API allows to send multiple rate policies at once. However, this property is very rarely used. We prefer to send rate policies one by one and simplify the architecture.

2020-01-10HID: hidraw, uhid: Always report EPOLLOUTJiri Kosina2-5/+7
hidraw and uhid device nodes are always available for writing so we should always report EPOLLOUT and EPOLLWRNORM bits, not only in the cases when there is nothing to read. Reported-by: Linus Torvalds <torvalds@linux-foundation.org> Fixes: be54e7461ffdc ("HID: uhid: Fix returning EPOLLOUT from uhid_char_poll") Fixes: 9f3b61dc1dd7b ("HID: hidraw: Fix returning EPOLLOUT from hidraw_poll") Signed-off-by: Jiri Kosina <jkosina@suse.cz>

ieee80211_rx_status off stack to IEEE80211_SKB_RXCB (skb->cb) removing the need to copy on to it. skb->cb is always present as a clean buffer so simply fill it in.

2020-01-10staging: vt6656: Fix false Tx excessive retries reporting.Malcolm Priestley1-2/+4
The driver reporting IEEE80211_TX_STAT_ACK is not being handled correctly. The driver should only report on TSR_TMO flag is not set indicating no transmission errors and when not IEEE80211_TX_CTL_NO_ACK is being requested.

2020-01-10staging: vt6656: use NULLFUCTION stack on mac80211Malcolm Priestley2-9/+6
It appears that the drivers does not go into power save correctly the NULL data packets are not being transmitted because it not enabled in mac80211. The driver needs to capture ieee80211_is_nullfunc headers and copy the duration_id to it's own duration data header.

2020-01-10staging: vt6656: correct packet types for CTS protect, mode.Malcolm Priestley2-4/+10
It appears that the driver still transmits in CTS protect mode even though it is not enabled in mac80211. That is both packet types PK_TYPE_11GA and PK_TYPE_11GB both use CTS protect. The only difference between them GA does not use B rates. Find if only B rate in GB or GA in protect mode otherwise transmit packets as PK_TYPE_11A.
