*	sys: general adoption of SPDX licensing ID tags.	Pedro F. Giffuni	2017-11-27	2	-0/+4
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

*	The TCP PAWS fix for kernels with fast tick rates (r231767) changed the TCP	Lawrence Stewart	2012-08-17	1	-4/+6
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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.

*	Import the ERTT (Enhanced Round Trip Time) Khelp module. ERTT uses the	Lawrence Stewart	2011-01-24	2	-0/+634
	Khelp/Hhook KPIs to hook into the TCP stack and maintain a per-connection, low noise estimate of the instantaneous RTT. ERTT's implementation is robust even in the face of delayed acknowledgements and/or TSO being in use for a connection. A high quality, low noise RTT estimate is a requirement for applications such as delay-based congestion control, for which we will be importing some algorithm implementations shortly.
