Currently the driver requests resources for the maximum theoretical bandwidth, when interface is brought up. Refine this process a bit: now the driver will request a small amount of resources when interface is up, and will only issue the maximum request when connected. This mechanism will be improved further in the future to make more refined requests based on actual bandwidth.

The length of file was always zero. The reason is: static ssize_t ath10k_debug_cal_data_read(struct file *file, char __user *user_buf, size_t count, loff_t *ppos) { struct ath10k *ar = file->private_data; void *buf = file->private_data; This is obviously bogus, private_data cannot contain both struct ath10k and the buffer. Fix it by caching calibration data to ar->debug.cal_data. This also allows it to be accessed when the device is not active (interface is down). The cal_data buffer is fixed size because during the first firmware probe we don't yet know what will be the lenght of the calibration data. It was simplest just to use a fixed length. There's a WARN_ON() in ath10k_debug_cal_data_fetch() if the buffer is too small. Tested with qca988x and firmware 10.2.4.70.56.

But this padding is not very specific to 4-address, it can happen even with three address + ethernet decap mode. Since the padding information can be obtained through Rx desc for QCA99X0 and newer chips, this hw_param is not needed any more.

In the chips doing this type of padding, the number of bytes padded will be indicated through msdu_end:info1. Define a hw_rx_desc_ops wrapper to retrieve the number of padded bytes and use this while doing undecap. This should fix padding related issues with ethernt decap format with QCA99X0, QCA9984, QCA9888 and QCA4019 hw.

So far driver does not use those new information for any functionalities, but there is one important information which is available from QCA99X0 onwards to indicate the number of bytes that hw padded at the begining of the rx payload and this information is needed to undecap the rx packet. Add an abstraction for Rx desc to make use of the new desc information available. The callback that this patch defines to retrieve the padding bytes will be used in follow-up patch.

This issue is originally reported in veriwave setup with 50 clients with TCP downlink traffic. While increasing number of clients, the average throughput drops gradually. With 50 clients, the combined peak throughput is decreased to 98 Mbps whereas reverting given commit restored it to 550 Mbps. Processing txqs for every tx completion is causing overhead. Ideally for management frame tx completion, pending txqs processing can be avoided. The change partly reverts the commit "ath10k: improve tx scheduling". Processing pending txqs after all skbs tx completion will yeild enough room to burst tx frames.
