2020-01-06wil6210: get rid of begin() and complete() ethtool_opsMichal Kubecek
The wil6210 driver locks a mutex in begin() ethtool_ops callback and unlocks it in complete() so that all ethtool requests are serialized. This is not going to work correctly with netlink interface; e.g. when ioctl triggers a netlink notification, netlink code would call begin() again while the mutex taken by ioctl code is still held by the same task. Let's get rid of the begin() and complete() callbacks and move the mutex locking into the remaining ethtool_ops handlers except get_drvinfo which only copies strings that are not changing so that there is no need for serialization.

2019-12-19wil6210: support set_multicast_to_unicast cfg80211 operationAhmad Masri
Wil6210 AP has a separate ring for transmitting multicast packets, multicast packets are transmitted without an ack from the receiver side. Therefore, 802.11 spec defines some low MCS rates for multicat packets. However, there is no guarantee that these packets were really received and handled on the client side. Some applications that rely on multicast packets, may prefer to transmit these packets as a unicast to ensure reliability, and also to ensure better performance with high MCS rates. multicast to unicast is done by duplicating multicast packets to all clients and changing the DA (multicast) to the MAC address of the client. see NL80211_CMD_SET_MULTICAST_TO_UNICAST for more info.

It was noticed that such situation gets even more reproducible, when the driver fails to enter bmps mode - which is highly likely to occur.

2019-12-13mac80211: Turn AQL into an NL80211_EXT_FEATUREToke Høiland-Jørgensen
Instead of just having an airtime flag in debugfs, turn AQL into a proper NL80211_EXT_FEATURE, so drivers can turn it on when they are ready, and so we also expose the presence of the feature to userspace. This also has the effect of flipping the default, so drivers have to opt in to using AQL instead of getting it by default with TXQs. To keep functionality the same as pre-patch, we set this feature for ath10k (which is where it is needed the most). While we're at it, split out the debugfs interface so AQL gets its own per-station debugfs file instead of using the 'airtime' file. [Johannes:] This effectively disables AQL for iwlwifi, where it fixes a number of issues: * TSO in iwlwifi is causing underflows and associated warnings in AQL * HE (802.11ax) rates aren't reported properly so at HE rates, AQL could never have a valid estimate (it'd use 6 Mbps instead of up to 2400!)

2019-12-02ath10k: enable napi on RX path for sdioWen Gong
For tcp RX, the quantity of tcp acks to remote is 1/2 of the quantity of tcp data from remote, then it will have many small length packets on TX path of sdio bus, then it reduce the RX packets's bandwidth of tcp. This patch enable napi on RX path, then the RX packet of tcp will not feed to tcp stack immeditely from mac80211 since GRO is enabled by default, it will feed to tcp stack after napi complete, if rx bundle is enabled, then it will feed to tcp stack one time for each bundle of RX. For example, RX bundle size is 32, then tcp stack will receive one large length packet, its length is neary 1500*32, then tcp stack will send a tcp ack for this large packet, this will reduce the tcp acks ratio from 1/2 to 1/32. This results in significant performance improvement for tcp RX. Tcp rx throughout is 240Mbps without this patch, and it arrive 390Mbps with this patch.
