Instead, we just need to create one, reuse it across all queues to reduce memory consumption further. And then we should take it into account the actual the host and the device MMC capability to determine what the appropriate xmit_buf_size can be. Both MT7921S and MT7663 can support up to Tx FIFO size of 0x3fe00 which means the device can receive 511 blocks of block size 512 in a row from the host. So if the driver aggregates the frames as many as possible the the device can support, we can merge multiple MMC requests into a single one to get rid of the overhead of the handling and synchronizing in those unnecessary MMC requests and reduce the SDIO lock contention with the Bluetooth concurrent traffic and finally to have the higher bus utilization with less idle cycle. With the patch, it is helpful for WiFi to have steady throughput performance especially while running Bluetooth concurrently.
