2019-02-28wil6210: add option to drop Tx packets when Tx ring is fullDedy Lansky3-2/+13
In AP mode with multiple clients, driver stops net queue (netif_tx_stop_queue) upon first ring (serving specific client) becoming full. This can have negative effect on transmission to other clients which may still have room in their corresponding rings. Implement new policy in which stop/wake net queue are not used. In case there is no room in the ring for a transmitted packet, drop the packet. New policy can be helpful to debug performance issues, to guarantee maximum utilization of net queues. New policy is disabled by default and can be enabled by debugfs: echo 1 > drop_if_ring_full Signed-off-by: Dedy Lansky <[email protected]> Signed-off-by: Maya Erez <[email protected]> Signed-off-by: Kalle Valo <[email protected]>

2019-02-28ath10k: Fill rx duration for each peer in fw_stats for WCN3990Surabhi Vishnoi6-6/+60
Currently, rx_duration for each peer is not getting populated in fw_stats debugfs entry for WCN3990. WCN3990 firmware sends rx duration for each peer as part of peer_extd_stats in WMI_UPDATE_STATS_EVENT. To enable peer_extd_stats, firmware expects host to send fw_stats_req_mask with flag WMI_TLV_PEER_STATS_EXTD set in WMI_REQUEST_STATS_CMD. Send fw_stats_req_mask with flag WMI_TLV_PEER_STATS_EXTD set in WMI_REQUEST_STATS_CMD and parse the peer_extd_stats in WMI_UPDATE_STATS_EVENT to populate the rx_duration of each peer in fw_stats debugfs entry. Currently the driver handles 32-bit rx_duration, but the rx_duration for WCN3990 can be upto 63 bit. The firmware sends rx_duration split into two 32-bit fields, with the upper 32-bits being valid only if its MSB is set. This change handles the 63-bit rx_duration obtained from WCN3990 and maintain the backward compatibility.

2019-02-28ath10k: Fix the wrong calculation ht_idx and idx of rate table for tx_statsSurabhi Vishnoi1-3/+3
ht_idx (ht rate index) and idx (rate table index) are calculated based on mcs index. This mcs index used in the above calculation should be 0-9 for getting the correct ht_idx and idx. Currently the mcs index used for the above calculations is mcs index which can be 0-31 (in case of HT), leading to incorrect rate index and ht index values. Fix the issue by obtaining mcs value from the ratecode reported by firmware and use it for calculating ht_idx and idx (rate-table index).

2019-02-28ath10k: Fix the wrong updation of BW in tx_stats debugfs entrySurabhi Vishnoi2-4/+5
Currently, the bandwidth is updated wrongly in BW table in tx_stats debugfs per sta as there is difference in number of bandwidth type in mac80211 and driver stats table. This leads to bandwidth getting updated at wrong index in bandwidth table in tx_stats.
