Subject: [PATCH 5/6] [IPROUTE2]: Cleanup: tc_calc_rtable()
commit e3bad6e344303fec9916d1420aade98a2e6c79cc
Author: Jesper Dangaard Brouer <hawk@...x.dk>
Date: Wed Sep 5 10:47:47 2007 +0200
[IPROUTE2]: Cleanup: tc_calc_rtable().
Change tc_calc_rtable() to take a tc_ratespec struct as an
argument. (cell_log still needs to be passed on as a parameter,
because -1 indicate that the cell_log needs to be computed by the
function.).
