+Subject: [PATCH 21/32] ivshmem-net: Fix stuck state machine during setup
+
+If the remote side is already in INIT state (or even higher) and has a
+cached rstate of RESET, we won't make progress when signaling RESET
+again because the remote side won't send a state update. Fix this by
+enforcing a local check after probe completion.
