Subject: [PATCH 3/6] [IPROUTE2]: Update pkt_sched.h (to resemble the kernel
	one)

commit ef065a43b8900fbc0763eac0fa0a9a8a00c8aaa2
Author: Jesper Dangaard Brouer <hawk@...x.dk>

    [IPROUTE2]: Update pkt_sched.h (to resemble the kernel one)
    
     Extend the tc_ratespec struct, with two parameters: 1) "cell_align"
     that allow adjusting the alignment of the rate table. 2) "overhead"
     that allow adding a packet overhead before the lookup in the kernel.
    
     This is done in order to, add support to changing the rate table to
     use the upper-boundry L2T (length to time) value. Currently we use the
     lower-boundry, which result in under-estimating the actual bandwidth
     usage.
