After the first batch of data has been processed by the driver the wifi chip may have more data ready to be read, which is managed by a loop in rtw_sdio_rx_isr(). It turns out that there are cases where the RX buffer length (from the REG_SDIO_RX0_REQ_LEN register) does not match the data we receive. The following two cases were observed with a RTL8723DS card: - RX length is smaller than the total packet length including overhead and actual data bytes (whose length is part of the buffer we read from the wifi chip and is stored in rtw_rx_pkt_stat.pkt_len). This can result in errors like: skbuff: skb_over_panic: text:ffff8000011924ac len:3341 put:3341 (one case observed was: RX buffer length = 1536 bytes but rtw_rx_pkt_stat.pkt_len = 1546 bytes, this is not valid as it means we need to read beyond the end of the buffer) - RX length looks valid but rtw_rx_pkt_stat.pkt_len is zero Check if the RX_REQUEST is set in the HISR register for each iteration inside rtw_sdio_rx_isr(). This mimics what the RTL8723DS vendor driver does and makes the driver only read more data if the RX_REQUEST bit is set (which seems to be a way for the card's hardware or firmware to tell the host that data is ready to be processed). For RTW_WCPU_11AC chips this check is not needed. The RTL8822BS vendor driver for example states that this check is unnecessary (but still uses it) and the RTL8822CS drops this check entirely.

The WiFi part is still 1x1 so the second antenna can be dedicated to Bluetooth - 0xd724 can only connect one antenna so it's shared between WiFi and Bluetooth Add a new entry for the single antenna RTL8723DS (0xd724) which can be found on the MangoPi MQ-Quad. Also rename the existing RTL8723DS entry (0xd723) so it's name reflects that it's the variant with support for two antennas.
