Subject: htb: Move direct_qlen code part to htb_parse_opt().
X-Git-Tag: v3.14.0~7
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4d4da09e0036107e7c49362b38df220e9a2f7b12;p=thirdparty%2Fiproute2.git

htb: Move direct_qlen code part to htb_parse_opt().

The direct_qlen command option is used with qdisc operation.
It happened to be implemented in htb_parse_class_opt() which is called
with class operation.
