+Subject: [PATCH] ivshmem-net: Fix bogus transition to RESET state
+
+If we are in READY but the remote is still in INIT, we so far fell back
+to RESET which caused the setup to get stuck. Fix this by only
+transitioning from READY/RUN to RESET in ivshm_net_state_change if the
+remote is in RESET as well.
