Message-ID: <20230920090412.726725-2-lizhijian@fujitsu.com> (raw)

From: Li Zhijian <lizhijian@cn.fujitsu.com>

Previously, we got a confusion error that complains
the RDMAControlHeader.repeat:
qemu-system-x86_64: rdma: Too many requests in this message (3638950032).Bailing.

Actually, it's caused by an unexpected RDMAControlHeader.type.
After this patch, error will become:
qemu-system-x86_64: Unknown control message QEMU FILE
