If anyone has any objections, please let me know. ------------------ From: Ryosuke Yasuoka [ Upstream commit 6671e352497ca4bb07a96c48e03907065ff77d8a ] When nci_rx_work() receives a zero-length payload packet, it should not discard the packet and exit the loop. Instead, it should continue processing subsequent packets.
