VF's command receive queue was mainly used to receive mailbox messages from PF. There are two type mailbox messages: request response message and message pushed by PF. There are two types of threads that can handle these messages: 1) the interrupt thread of the main process: it could handle both types of messages. 2) other threads: it could only handle request response messages. The collaboration mechanism between the two type threads is that other threads set the opcode of processed messages to zero so that the interrupt thread of the main process does not process these messages again. Because other threads can only process part of the messages, after the processing is complete, the next-to-use pointer of the command receive queue should not be updated. Otherwise, some messages (e.g. messages pushed by PF) maybe discarded. Unfortunately, the patch to be reverted updates next-to-use pointer of the command receive queue in other threads context, and this will lead to discard some mailbox message.
