Subject: parser: allow quoted string in flowtable_expr_member
X-Git-Tag: v1.0.2~47
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=07af4429241c9832a613cb8620331ac54257d9df;p=thirdparty%2Fnftables.git

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.
