Definition 'PCIE_P2P_MAX' is '3'. The value here is not a MAXimum. It is a count or a number. It is how many masks there are. The masks are numbered 0, 1, 2 so the maximum is 2. Hence rename variable into 'PCIE_P2P_CNT' which is a more accurate name. Suggested-by:

Currently, wfx_update_filtering() apply the value of wvif->filter_mcast to the hardware. But an attentive reader will note that wfx_update_filtering() is always called after set wvif->filter_mcast. Thus, it not necessary to store filter_mcast in the struct wfx_vif. We can just pass it as parameter. Also rename wfx_update_filtering() in wfx_filter_mcast() to reflect this change. Signed-off-by:

Currently, wfx_update_filtering() is sometime called only to apply the value of wvif->filter_beacon to the hardware. It is nicer to have a specific function for beacon filtering. In add, an attentive reader would note that wfx_update_filtering() is always called after change of wvif->filter_beacon. Thus, it not necessary to store filter_beacon in the struct wfx_vif. We can just pass it as parameter. Signed-off-by:

hif_set_rx_filter() apply changes on filter_prbreq and filter_bssid to the hardware. Each time filter_prbreq and filter_bssid are changed, hif_set_rx_filter() is called. Currently, on extra call to hif_set_rx_filter() is made from wfx_update_filtering(). This call is useless. Drop it. Signed-off-by:

Device is able to automatically reply to probe request (therefore, the probe requests are not forwarded to host). This feature is enabled by wfx_start_ap(). However, further calls to wfx_configure_filter() can disable it. So, relocate the handling of probe request filtering in wfx_configure_filter(). Note that wfx_configure_filter() is always called by mac80211 when an AP start. Signed-off-by:

It is not very clear why driver ask to firmware to stop filtering probe request during scan. It is particularly weird because scan is not supported in AP mode. In add, it does not restore previous filtering state after scanning. It seems to be a mistake and should be dropped. Signed-off-by:

The only reason we ask to mac80211 to wait for a dtim before to associate is to get an accurate DTIM value. However, we can temporary set the dtim period to 1. Then we can waiting for BSS_CHANGED_BEACON_INFO for the real value. Thus, the association process is faster. Signed-off-by:

When the device joins an AP, beacon are forwarded to the host. Once has retrieved all necessary parameters, we can start to filter the beacon (and only beacon with changed/new data will be forwarded). Currently, the driver detect beacons in data Rx process. It is far more easier to just wait for the BSS_CHANGED_BEACON_INFO event. Signed-off-by:

Currently, filtering are not update if the device is not connected. There is no obvious rationale for that. Updating filtering while it is not necessary is harmless. On the other hand, it is difficult to ensure that the filtering rule has been correctly sent to the firmware. Just drop this useless condition. Signed-off-by:

MT7621 has three assigned interrupts for the pcie. This interrupts should properly being mapped taking into account which devices are finally connected in which bus according to link status. So the irq mappings should be as follows according to link status (three bits indicating which devices are link up): * For PCIe Bus 1 slot 0: - status = 0x2 || status = 0x6 => IRQ = pcie1_irq (24). - status = 0x4 => IRQ = pcie2_irq (25). - default => IRQ = pcie0_irq (23). * For PCIe Bus 2 slot 0: - status = 0x5 || status = 0x6 => IRQ = pcie2_irq (25). - default => IRQ = pcie1_irq (24). * For PCIe Bus 2 slot 1: - status = 0x5 || status = 0x6 => IRQ = pcie2_irq (25). - default => IRQ = pcie1_irq (24). * For PCIe Bus 3 any slot: - default => IRQ = pcie2_irq (25). Because of this, the function 'of_irq_parse_and_map_pci' cannot be used and we need to change device tree information from using the 'interrupt-map' and 'interrupt-map-mask' properties into an 'interrupts' property to be able to get irq information from the ports using the 'platform_get_irq' and storing an 'irq-map' into the pcie driver data node to properly map correct irq using a new 'mt7621_map_irq' function where this map will be read and the correct irq returned.

Pcie phy for pcie0 and pcie1 is shared using a dual ported one. Current code was assuming that if nothing is connected in pcie0 it won't be also nothing connected in pcie1. This assumtion is wrong for some devices such us 'Mikrotik rbm33g' and 'ZyXEL LTE3301-PLUS' where only connecting a card to the second bus on the phy is possible. For such devices kernel hangs in the same point because of the wrong poweroff of the phy getting the following trace: mt7621-pci-phy 1e149000.pcie-phy: PHY for 0xbe149000 (dual port = 1) mt7621-pci-phy 1e14a000.pcie-phy: PHY for 0xbe14a000 (dual port = 0) mt7621-pci-phy 1e149000.pcie-phy: Xtal is 40MHz mt7621-pci-phy 1e14a000.pcie-phy: Xtal is 40MHz mt7621-pci 1e140000.pcie: pcie0 no card, disable it (RST & CLK) [hangs] The wrong assumption is located in the 'mt7621_pcie_init_ports' function where we are just making a power off of the phy for slots 0 and 2 if nothing is connected in them. Hence, only poweroff the phy if nothing is connected in both slot 0 and slot 1 avoiding the kernel to hang.
