Randall Stewart 9903bf34f0 tcp: rack pacing has some caveats that need to be obeyed when LRO is missing
n further non-LRO testing I found a case where rack is supposed to be waking up but
it is not now. In this special case it sets the flag rc_ack_can_sendout_data. When that is
set we should not prohibit output.

FreeBSD Kernel Source:

This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.

Kernel configuration files are located in the conf/ subdirectory of each architecture. GENERIC is the configuration used in release builds. NOTES contains documentation of all possible entries. LINT is a compile-only configuration used to maximize build coverage and detect regressions.
