To save time - if you built HTB as a module, you can probably (well it worked for me) get away with editing htb.c and do make SUBDIRS=net/sched modules and replacing /lib/modules/[kversion]/ker

I imagine that 106 value is a reference to this post: http://mailman.ds9a.nl/pipermail/lartc/2004q2/012369.html ... It's my suspicion that the MPU and overhead options for HTB would assist in resolving this and enable me to resume using 190kbit instead of 160kbit for the outer most parent cl

It seems Andreas Klauer's fairnat has experimental support for using HTB's MPU and overhead options. fairnat.config: # Use MPU for HTB. From the LARTC Howto on MPU: # "A zero-sized packet does not use zero bandwidth. For ethernet, no packet # uses less than 64 bytes. The Minimum Packet Unit det
