Usually things of this sort > MFC'd after 4 weeks, but I thought I'd get confirmation. As noted in the commit message, I do indeed plan to MFC this in about a week. There are two remaining issues in some drivers that may result in packet reordering (w/ or w/o ALTQ). I was hoping to address this before the MFC, but I didn't yet find the time. Regards, Max
