mt7615_load_patch in mt7615/mcu.c sometimes fails with: mt7622-wmac 18000000.wmac: Failed to get patch semaphore and returns -EAGAIN. But this error is returned all the way up to mt7615_init_work with no actual retrial performed, leaving a broken wireless phy. Wait a bit and retry for up to 10 times before giving up. Signed-off-by:

Added multiple queues[BK,BE,VI,VO] to handle different priority data packets. Before adding a packet to the queue, checked its priority from the header, and then add to the suitable queue. The limit for each queue is maintained separately. Also while passing the packets to the firmware via VMM take care to select data packets based on priority and available space. Signed-off-by:

Some AP will not follow the power save request, or it cannot stop transmission until its queue is empty. It may bring the decreasing of data rate. WLAN firmware will count is the AP still leaked packet after power save handshake was done or not to enable WLAN slot extend mechanism. The extend WLAN slot mechanism will extend the WLAN slot after power save handshake, 5 ms per times, maximum is 5 times to received the leaked packet to avoid the rate lower down. And if the transmission was already locked at CCK rate. The extended WLAN slot can also increase the opportunity that we can received the CCK's long packet and be released from CCK rate. While BT multi-link status was finished, there is possible that it still has some packet remained for seconds. Add a timer to remain the multi-link mechanism to protect WLAN Rx. Signed-off-by:

This reverts commit 28606150. Since actually Buffalo WI-U3-866D is falied to power on with the change. The rtl8812au driver code to power on is same with the rtl8821a code. But the rtl8821ae included rtl8821a does not support USB interface. So seems that rtl8812au should be supported by rt1l8821a code with USB. Signed-off-by:

The driver_data area of ieee80211_tx_info is used in ath11k for ath11k_skb_cb. The first function in the TX patch which rewrites it to ath11k_skb_cb is already ath11k_mac_op_tx. No one else in the code path must use it for something else before it reinitializes it. Otherwise the data has to be considered uninitialized or corrupt. But the ieee80211_tx_info.control shares exactly the same area as ieee80211_tx_info.driver_data and ath11k is still using it. This results in best case in a ath11k c000000.wifi1: no vif found for mgmt frame, flags 0x0 or (slightly worse) in a kernel oops. Instead, the interesting data must be moved first into the ath11k_skb_cb and ieee80211_tx_info.control must then not be used anymore.
