   4 Subject: [PATCH 29/32] ivshmem-net: Fix bogus transition to RESET state
   5
   6 If we are in READY but the remote is still in INIT, we so far fell back
   7 to RESET which caused the setup to get stuck. Fix this by only
   8 transitioning from READY/RUN to RESET in ivshm_net_state_change if the
   9 remote is in RESET as well.
