Subject: QoS: Drop support for setting TOS bits per class
X-Git-Tag: v2.23-core137~60
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=3174d9c6b610c1f1ce1e7a8828a4575def2e2392;p=ipfire-2.x.git

QoS: Drop support for setting TOS bits per class

This is useless since no ISP will evaluate those settings
any more and it has a rather large impact on throughput.
