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.

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.

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]>

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.

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.

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.

Commit 503c1fb ("cfg80211/nl80211: add a port authorized event") added the NL80211_CMD_PORT_AUTHORIZED event to indicate that a connection is authorized. It replaced the PORT_AUTHORIZED attribute and the authorized flag added in commit f45cbe6 ("nl80211: add authorized flag to ROAM event").

When using PORT_AUTHORIZED event mechanism for offload FT, wpa_supplicant started a full EAP exchange after a successful roaming.
