Since device can pass multiple frames in a single payload temporary Rx buffer was big enough to hold all of them; now the driver can concatenate a single frame from multiple payloads. The Rx buffer size may be configured via tunable (dev.rtwn.%d.rx_buf_size). Tested with: - rtl8188cus, rtl8188eu and rtl8821au (STA mode). - (by kevlo) rtl8192cu and rtl8188eu.
