SVN rev 214875 on 2010-11-06 13:03:33Z by lstewart
MFC r209662,209665:
Import the Statistical Information For TCP Research (SIFTR) kernel module into
FreeBSD. SIFTR logs a range of statistics on active TCP connections to a log
file, providing the ability to make highly granular measurements of TCP
connection state. The tool is aimed at system administrators, developers and
researchers alike. Please take it for a spin and test it out - the man page
should have all the information required to get you going.
Many thanks go to the Cisco University Research Program Fund at Community
Foundation Silicon Valley and the FreeBSD Foundation. Their support of our work
at the Centre for Advanced Internet Architectures, Swinburne University of
Technology is greatly appreciated.
The base SIFTR code from r209662 was modified as part of this MFC in order to
work correctly on FreeBSD 7.
r209980:
Catch up with the rename of DPCPU_SUM to DPCPU_VARSUM.
r209982:
The SIFTR DPCPU statistics struct was not being zeroed between enable/disable
cycles so the values would accumulate rather than reset for each cycle.
