*	tcp: fix build issue for some cc modules	Michael Tuexen	2023-07-13	1	-3/+3
\| \| \| \| \| \| \| \| \| \| \| \|	The TCP_HHOOK option was moved from opt_inet.h to opt_global.h in https://cgit.FreeBSD.org/src/commit/?id=e68b3792440cac248347afe08ba5881a00ba6523 The corresponding changes in two Makefiles were missed, which resulted in not building cc_cdg, cc_chd, cc_hd, and cc_vegas anymore.

*	In the TCP stack, the hhook(9) framework provides hooks for kernel modules	Jonathan T. Looney	2016-10-12	1	-1/+9
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	to add actions that run when a TCP frame is sent or received on a TCP session in the ESTABLISHED state. In the base tree, this functionality is only used for the h_ertt module, which is used by the cc_cdg, cc_chd, cc_hd, and cc_vegas congestion control modules. Presently, we incur overhead to check for hooks each time a TCP frame is sent or received on an ESTABLISHED TCP session. This change adds a new compile-time option (TCP_HHOOK) to determine whether to include the hhook(9) framework for TCP. To retain backwards compatibility, I added the TCP_HHOOK option to every configuration file that already defined "options INET". (Therefore, this patch introduces no functional change. In order to see a functional difference, you need to compile a custom kernel without the TCP_HHOOK option.) This change will allow users to easily exclude this functionality from their kernel, should they wish to do so. Note that any users who use a custom kernel configuration and use one of the congestion control modules listed above will need to add the TCP_HHOOK option to their kernel configuration.

*	Import the ERTT (Enhanced Round Trip Time) Khelp module. ERTT uses the	Lawrence Stewart	2011-01-24	2	-1/+10
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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.
