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. Note that TXCTL_CREDITS can't be larger than the firmware default credit update threshold 2; otherwise there will be a deadlock for both side waiting for each other.

2020-05-06brcmfmac: Add P2P Action Frame retry delay to fix GAS Comeback Response ↵Justin Li
failure issue It was observed that P2P Cert. 5.1.19: DEVUT responds to Service Discovery request failed due to DUT did not send GAS Comeback Response after receiving request from test bed P2P peer. To fix this issue, we need to add P2P Action Frame retry delay to enhance P2P connection under VSDB and noisy environment, since the peer can be in other channels under VSDB.

2020-05-04brcmfmac: no need to check return value of debugfs_create functionsGreg Kroah-Hartman
When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. In doing this, make brcmf_debugfs_add_entry() return void as no one was even paying attention to the return value.

2020-05-04brcmfmac: remove arp_hostip_clear from brcmf_netdev_stopWright Feng
The firmware does not respond ARP request and causes ping failure with following steps: 1. Bring up interface ifconfig wlan0 up or start wpa_supplicant 2. Set the IP address ifconfig wlan0 192.168.100.10 3. Bring down interface or ifconfig wlan0 down or kill wpa_supplicant 4. Bring up interface again and set the same IP address 5. Connect to AP(192.168.100.1) and ping to AP will be failed. FMAC clears arp_hostip when bringing down the interface, but not set it back if setting the same IP address. We are able to see the IP address in interface info(inconfig wlan0) but the ping still cannot work because the firmware ARP offload does not respond the ARP request. Because of that, we remove "arp_hostip_clear" from function "brcmf_netdev_stop" Signed-off-by: Wright Feng <wright.feng@cypress.com> Signed-off-by: Chi-Hsien Lin <chi-hsien.lin@cypress.com> Reviewed-by: Franky Lin <franky.lin@broadcom.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/1587970803-77700-3-git-send-email-chi-hsien.lin@cypress.com

2020-04-24cfg80211: change internal management frame registration APIJohannes Berg
Almost all drivers below cfg80211 get the API wrong (except for cfg80211) and are unable to cope with multiple registrations for the same frame type, which is valid due to the match filter. This seems to indicate the API is wrong, and we should maintain the full information in cfg80211 instead of the drivers. Change the API to no longer inform the driver about individual registrations and unregistrations, but rather every time about the entire state of the entire wiphy and single wdev, whenever it may have changed. This also simplifies the code in cfg80211 as it no longer has to track exactly what was unregistered and can free things immediately.
