Change subject: Fix DNS options duplication on PUSH_UPDATE
......................................................................
Fix DNS options duplication on PUSH_UPDATE
Commit
2dfc4f ("dns: deal with --dhcp-options when --dns is active")
has removed reset of tuntap DNS options. Due to that, incoming --dns
options are added to existing ones instead of overwriting them.
It has also added a new storage for --dhcp-option. The push-update
code didn't clear it and as a result, incoming --dhcp-option options
were added to existing ones instead of overwriting them.
Fixed by:
- resetting tuntap DNS options (regression from abovementioned commit)
- clearing dhcp options storage in push-update code
