Make "tr /t" start backtraces from the switchframe like we do on other architectures (e.g. amd64 and sparc64).
enable af_frame. this paves the way for lldp support in base.
Fix some spelling.
Implement a ddb.suspend sysctl that may help debugging suspend/resume bugs. When this sysctl is set to 1, it will force "S0ix" suspend and skip suspend of inteldrm(4) and amdgpu(4) such that the display remains on during suspend. That should make anything printed on the console to be visible. Power consumption will probably suck though.
ngbe(4): do not call ifq_restart() if no space was made on tx ring
Carefully prune sysctl nodes with #ifndef SMALL_KERNEL recover space lost to other bloaty software. ok bluhm
Reinstate MP_LOCKDEBUG support for mutexes

Get rid of unused `so' argument in sbspace(). No functional changes.
Put the bowels of the various VOP_PRINT routines under defined(DEBUG) || defined(DIAGNOSTIC) || defined(VFSLCKDEBUG) as they won't be used otherwise.
Unlock IPCTL_MTUDISC case of ip_sysctl().
remove some unused functions ok stsp@
Push netlock down to mrt{,6}_sysctl_mfc().
Cache route per softnet thread with netstack.
Do not depend on RW_SLEEPFAIL in ntfs_ntlookup
Protect mbuf statistics counter with splnet.
Remove misleading comment.
