Hi Jani,

Basically using vrr.enable while computing AS SDP preventing VRR to enable/disable
With fastest. Patch  is intended to compute AS SDP so that VRR can be enabled/disabled using fastest.

With changing the header has triggered new patch series: https://patchwork.freedesktop.org/series/139340/

Can you please help on review ?
