From: Ryosuke Yasuoka <ryasuoka@redhat.com> stable inclusion from stable-v6.6.33 commit 46e72ebc6b35156d0a4218f4bb9c6f03c9c80454 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAD6H2 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ 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.
