Hi Oliver,

I just stumbled over:
	
• TCP Prague will always use Accurate ECN, regardless of the net.ipv4.tcp_ecn value. This eases up concurrent testing of different CCA that may or may not want to use ECN (e.g., plain non-ECN cubic).

I assume that this is only for testing and not supposed to be the default for an eventual up-stream submission of tcp prague?

Sebastian
