Subject: Revert "upstream: Update default IPQoS in ssh(1), sshd(8) to DSCP
AF21 for"
This reverts commit 5ee8448ad7c306f05a9f56769f95336a8269f379.
The IPQoS default changes have some unfortunate interactions with
iptables (see https://bugs.debian.org/923880) and VMware, so I'm
temporarily reverting them until those have been fixed.
