Subject: [PULL 09/16] migration/rdma: It makes no sense to recive that flag without RDMA
Date: Fri,  5 May 2023 02:48:05 +0200	[thread overview]
Message-ID: <20230505004812.31583-10-quintela@redhat.com> (raw)
In-Reply-To: <20230505004812.31583-1-quintela@redhat.com>

This could only happen if the source sent
RAM_SAVE_FLAG_HOOK (i.e. rdma) and destination don't have CONFIG_RDMA.
