From 4a5c9903f3164cef134e7f81b361b3fa7d5c0b52 Mon Sep 17 00:00:00 2001 From: Yuval Shaia Date: Fri, 21 Dec 2018 16:40:24 +0200 Subject: [PATCH] qapi: Define new QMP message for pvrdma pvrdma requires that the same GID attached to it will be attached to the backend device in the host. A new QMP messages is defined so pvrdma device can broadcast any change made to its GID table. This event is captured by libvirt which in turn will update the GID table in the backend device.
