   4 Subject: [PATCH] parser: allow quoted string in flowtable_expr_member
   5
   6 Devices with interface names starting with a digit can not be configured
   7 in flowtables. Trying to do so throws the following error:
   8
   9 Error: syntax error, unexpected number, expecting comma or '}'
  10 devices = { eth0, 6in4-wan6 };
  11
  12 This is however a perfectly valid interface name. Solve the issue by
  13 allowing the use of quoted strings.
