2020-07-14brcm80211: brcmsmac: Move LEDs to GPIO descriptorsLinus Walleij
The code in the BRCM80211 BRCMSMAC driver is using the legacy GPIO API to to a complex check of the validity of the base of the GPIO chip and whether it is present at all and then adding an offset to the base of the chip. Use the existing function to obtain a GPIO line internally from a GPIO chip so we can use the offset directly and modernize the code to use GPIO descriptors instead of integers from the global GPIO numberspace.

2020-07-14brcmfmac: Transform compatible string for FW loadingMatthias Brugger
The driver relies on the compatible string from DT to determine which FW configuration file it should load. The DTS spec allows for '/' as part of the compatible string. We change this to '-' so that we will still be able to load the config file, even when the compatible has a '/'. This fixes explicitly the firmware loading for "solidrun,cubox-i/q".

2020-07-14brcmfmac: set pacing shift before transmitting skb to busWright Feng
Linux 3.6 introduces TSQ which has a per socket threshold for TCP Tx packet to reduce latency. In flow control mode, host driver enqueues skb in hanger and TCP doesn't push new skb frees until host frees the skb when receiving fwstatus event. So set pacing shift 8 to send them as a single large aggregate frame to the bus layer. 43455 TX TCP throughput in different FC modes on Linux 5.4.18 sk_pacing_shift : Throughput (fcmode=0) 10: 245 Mbps 9: 245 Mbps 8: 246 Mbps 7: 246 Mbps sk_pacing_shift : Throughput (fcmode=1) 10: 182 Mbps 9: 197 Mbps 8: 206 Mbps 7: 207 Mbps sk_pacing_shift : Throughput (fcmode=2) 10: 180 Mbps 9: 197 Mbps 8: 206 Mbps 7: 207 Mbps Signed-off-by: Wright Feng <wright.feng@cypress.com> Signed-off-by: Chi-hsien Lin <chi-hsien.lin@cypress.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/20200624091608.25154-3-wright.feng@cypress.com
2020-07-14brcmfmac: set state of hanger slot to FREE when flushing PSQWright Feng
When USB or SDIO device got abnormal bus disconnection, host driver tried to clean up the skbs in PSQ and TXQ (The skb's pointer in hanger slot linked to PSQ and TSQ), so we should set the state of skb hanger slot to BRCMF_FWS_HANGER_ITEM_STATE_FREE before freeing skb. In brcmf_fws_bus_txq_cleanup it already sets BRCMF_FWS_HANGER_ITEM_STATE_FREE before freeing skb, therefore we add the same thing in brcmf_fws_psq_flush to avoid following warning message.

2020-07-14brcmfmac: reserve 2 credits for host tx control pathAmar Shankar
It is observed that sometimes when sdiod is low in tx credits in low rssi scenarios, the data path consumes all sdiod rx all credits and there is no sdiod rx credit available for control path causing host and card to go out of sync resulting in link loss between host and card. So in order to prevent it some credits are reserved for control path.

2020-05-29b43_legacy: Fix connection problem with WPA3Larry Finger
Since the driver was first introduced into the kernel, it has only handled the ciphers associated with WEP, WPA, and WPA2. It fails with WPA3 even though mac80211 can handle those additional ciphers in software, b43legacy did not report that it could handle them. By setting MFP_CAPABLE using ieee80211_set_hw(), the problem is fixed. With this change, b43legacy will handle the ciphers it knows in hardware, and let mac80211 handle the others in software. It is not necessary to use the module parameter NOHWCRYPT to turn hardware encryption off. Although this change essentially eliminates that module parameter, I am choosing to keep it for cases where the hardware is broken, and software encryption is required for all ciphers.

2020-05-29b43: Fix connection problem with WPA3Larry Finger
Since the driver was first introduced into the kernel, it has only handled the ciphers associated with WEP, WPA, and WPA2. It fails with WPA3 even though mac80211 can handle those additional ciphers in software, b43 did not report that it could handle them. By setting MFP_CAPABLE using ieee80211_set_hw(), the problem is fixed. With this change, b43 will handle the ciphers it knows in hardware, and let mac80211 handle the others in software. It is not necessary to use the module parameter NOHWCRYPT to turn hardware encryption off. Although this change essentially eliminates that module parameter, I am choosing to keep it for cases where the hardware is broken, and software encryption is required for all ciphers.

2020-05-13brcmfmac: fix WPA/WPA2-PSK 4-way handshake offload and SAE offload failuresChung-Hsien Hsu
An incorrect value of use_fwsup is set for 4-way handshake offload for WPA//WPA2-PSK, caused by commit 3b1e0a7bdfee ("brcmfmac: add support for SAE authentication offload"). It results in missing bit BRCMF_VIF_STATUS_EAP_SUCCESS set in brcmf_is_linkup() and causes the failure. This patch correct the value for the case. Also setting bit BRCMF_VIF_STATUS_EAP_SUCCESS for SAE offload case in brcmf_is_linkup() to fix SAE offload failure.

The driver sends an action frame down and waits for dwell time to be completed or aborted before sending out the next action frame.

2020-05-12brcmfmac: map 802.1d priority to precedence level based on AP WMM paramsSaravanan Shanmugham
In WLAN, priority among various access categories of traffic is always set by the AP using WMM parameters and this may not always follow the standard 802.1d priority. In this change, priority is adjusted based on the AP WMM params received as part of the Assoc Response and the same is later used to map the priority of all incoming traffic. In a specific scenario where EDCA parameters are configured to be same for all ACs, use the default FW priority definition to avoid queuing packets of all ACs to the same priority queue.
