Set F2 blocksize to 256 bytes for 4373. It fixes DMA error while having UDP bi-directional traffic. Signed-off-by: Wright Feng <[email protected]> Signed-off-by: Chi-hsien Lin <[email protected]>
broken_sg_support, sd_head_align, and sd_sgentry_align are used in brcmfmac code but not configurable in dts file. Add the parsing logic. Now they can be configured like below in dts: brcm,broken_sg_support; brcm,sd_head_align = /bits/ 16 <4>; brcm,sd_sgentry_align = /bits/ 16 <4>; Signed-off-by: Chi-hsien Lin <[email protected]>
APSTA can work on two band concurrently with using VSDB(Virtual Simultaneous Dual-Band) or RSDB(Real Simultaneous Dual-Band) features. In this case, we have to keep apsta is 1 in firmware side. If we start wpa_supplicant on wlan0 and then start hostapd on wlan1, the apsta will be set to 0, and data will be stall on wlan0(station). Because that, we only set apsta to 0 when AP start on primary interface. Signed-off-by: Wright Feng <[email protected]> Signed-off-by: Chi-hsien Lin <[email protected]>
Hostap daemon has a parameter "ap_isolate which is used to prevent low-level bridging of frames between associated stations in the BSS. For driver side, we add cfg80211 ops method change_bss to support setting AP isolation from user space. Signed-off-by: Wright Feng <[email protected]> Signed-off-by: Chi-hsien Lin <[email protected]>
When eap_restrict is enabled, firmware will toss non-802.1x frames from tx/rx data path if station not yet authorized. Internal firmware eap_restrict is disabled by default. This patch makes it possible to enable firmware eap_restrict by specifying eap_restrict=1 as module parameter.

Host driver needs to provide a dummy wowlan filter for kernel and provided the the well configured wowlan stack. So the system will keep driver in connected state in suspend mode and can be wake up by ping packet. Enable unicast packet filter before system suspend and disable it after resume.

Set wowl configuration in disconnect state is redundant. Remove it to fix no scan result issue after resume. Signed-off-by: Double Lo <[email protected]> Signed-off-by: Chi-hsien Lin <[email protected]>
With setting sdio_wq_highpri=1 in module parameters, tasks submitted to SDIO workqueue will put at the head of the queue and run immediately. This parameter is for getting higher TX/RX throughput with SDIO bus. Signed-off-by: Wright Feng <[email protected]> Signed-off-by: Chi-hsien Lin <[email protected]>
The firmware does not respond ARP request and causes ping failed 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 <[email protected]> Signed-off-by: Chi-hsien Lin <[email protected]>
Send P2P Presence Response from the p2p interface address instead of the p2p device address. Signed-off-by: Madhan Mohan R <[email protected]> Signed-off-by: Chi-hsien Lin <[email protected]>
P2p spec mentioned that the p2p device address should be the globally administered address with locally administered bit set. Therefore, follow this guideline by default. When the primary interface is set to a locally administered address, the locally administered bit cannot be set again. Generate a random locally administered address for this case.

commit 2bc50d8 upstream. Will enable FMAC to push more packets to bus tx queue and help improve throughput when fws queuing is enabled. This change is required to tune the throughput for passing WMM CERT tests.

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. This change should fix the following 802.11n certification tests: * 5.2.31 ACM Bit Conformance test * 5.2.32 AC Parameter Modification test Signed-off-by: Saravanan Shanmugham <[email protected]> Signed-off-by: Chi-hsien Lin <[email protected]>
When USB or SDIO device got abnormal bus disconnection, host driver tried to clean up the SKBs in PSQ and TXQ. The SKBs pointer in hanger 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 set BRCMF_FWS_HANGER_ITEM_STATE_FREE before freeing SKB, therefore we add this in brcmf_fws_psq_flush to avoid following warning message.

This is a port of the virtual ALSA AVB driver by indu for BBB and BBAI. It is based on: https://github.com/induarun9086/beagleboard-linux/blob/4.4/sound/drivers/avb.c
It was implemented during GSoC 2020 for the project Media Ip Streaming.
Usage description and documentation can be found here: https://niklaswan.github.io/GSoC-Overview/avb-alsa/
