X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f71b109f1730902b73f70d78764d8a41265080dd;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

net sched actions police: peg drop stats for conforming traffic

setting conforming action to drop is a valid policy.
When it is set we need to at least see the stats indicating it
for debugging.
