I'm trying to figure out my RSKM by using TQ and the rskm_report command. So I suppose that if TQ won't report it, then I have use the Tsu and Thld times reported by TQ to calculate the RSKM.

RSKM = (TUI - SW - TCCS)/2

TUI : Time Unit Interval

SW : Sampling Window

TCCS: Transmitter channel to channel skew

Tsw = Tsu + Thd + PLL jitter
