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