Austin Shafer 65de0f1855 LinuxKPI: 802.11: fix ieee80211_schedule_txq() to avoid rtw89 panic
rtw89 TX path was faulting in linuxkpi_ieee80211_next_txq() due to a
"double scheduling" check in linuxkpI_ieee80211_schedule_txq() being
incorrect:
the next pointer may be NULL there if the element is the last in the
tailq, so correctly check tqe_prev.  Without the fix we may have queued
the same element to the tailq twice, and because it was the last element
and had a NULL tqe_next, that NULL value would get propogated into
another node's tqe_prev on removal, and other such nastiness.

With this rtw89 no longer panics.

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.

Documentation:

Source code documentation is maintained in a set of man pages, under section 9. These pages are located in share/man/man9, from the top-level of the src tree. Consult intro(9) for an overview of existing pages.

Some additional high-level documentation of the kernel is maintained in the Architecture Handbook.
