The method ndo_start_xmit() is defined as returning an 'netdev_tx_t', which is a typedef for an enum type defining 'NETDEV_TX_OK' but this driver returns '0' instead of 'NETDEV_TX_OK'. Fix this by returning 'NETDEV_TX_OK' instead of '0'. Signed-off-by:

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.

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". Signed-off-by:

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:

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.

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. Signed-off-by:

brcmfmac host driver makes SDIO bus sleep and stops SDIO watchdog if no pending event or data. As a result, host driver does not poll firmware console buffer before buffer overflow, which leads to missing firmware logs. We should not stop SDIO watchdog if console_interval is non-zero in debug build. Signed-off-by:

WILC1000 is an IEEE 802.11 b/g/n IoT link controller module. The WILC1000 connects to Microchip AVR/SMART MCUs, SMART MPUs, and other processors with minimal resource requirements with a simple SPI/SDIO-to-Wi-Fi interface. WILC1000 driver has been part of staging for few years. With contributions from the community, it has improved significantly. Full driver review has helped in achieving the current state. The details for those reviews are captured in 1 & 2.

Currently need ptk/gtk wmi peer flags in wmi peer assoc cmd are set based on the rsnie and wpaie of the bss from the bss list. Since this bss list is not updated with current BSSID for AP mode, we may not find bss from the bss list. Which results in ptk/gtk peer flags are not set in the wmi peer assoc cmd. Due to this EAPOL frames are going in data rates instead of management rates. Tested-on: IPQ8074 WLAN.HK.2.1.0.1-01228-QCAHKSWPL_SILICONZ-1 Signed-off-by:
