Firecracker v1.9.1

Fixed

• #4824: Add
  missing configuration of tap offload features when restoring from a snapshot.
  Setting the features was previously
  moved
  from net device creation to device activation time, but it was not reflected
  in the restore path. This was leading to inability to connect to the restored
  VM if the offload features were used.
• #4829: v1.9.0
  was missing most of the debugging information in the debuginfo file, due to a
  change in the Cargo defaults. This has been corrected.
