I'm currently using ALTQ successfully with the em driver, so if igb behaved the same with respect to using if_start instead of if_transmit when ALTQ is in play, that would be great. I do not completely understand the change you propose as I am not very familiar with the driver internals. Any kind of patch or extra Makefile/make.conf definition that would allow me to build a 9-STABLE kernel with an igb driver that works again with ALTQ, ASAP, would be much appreciated. > > Jack > > > > On Thu, Mar 28, 2013 at 2:31 PM, Nick Rogers wrote: >> >> On Tue, Dec 11, 2012 at 1:09 AM, Jack Vogel wrote: >> > On Mon, Dec 10, 2012 at 11:58 PM, Gleb Smirnoff >> > wrote: >> > >> >> On Mon, Dec 10, 2012 at 03:31:19PM -0800, Jack Vogel wrote: >> >> J> UH, maybe asking the owner of the driver would help :) >> >> J> >> >> J> ... and no, I've never been aware of doing anything to stop >> >> supporting >> >> altq >> >> J> so you wouldn't see any commits.
