Lawrence Stewart ee24d3b840 The TCP PAWS fix for kernels with fast tick rates (r231767) changed the TCP ... timestamp related stack variables to reference ms directly instead of ticks. The h_ertt(4) Khelp module relies on TCP timestamp information in order to calculate its enhanced RTT estimates, but was not updated as part of r231767. Consequently, h_ertt has not been calculating correct RTT estimates since r231767 was comitted, which in turn broke all delay-based congestion control algorithms because they rely on the h_ertt RTT estimates. Fix the breakage by switching h_ertt to use tcp_ts_getticks() in place of all previous uses of the ticks variable. This ensures all timestamp related variables in h_ertt use the same units as the TCP stack and therefore results in meaningful comparisons and RTT estimate calculations.
