    Subject[patch 14/60] pktgen: do not access flows[] beyond its length
    -stable review patch.  If anyone has any objections, please let us know.

    ------------------
    From: Florian Westphal <fw@strlen.de>

    [ Upstream commit 5b5f792a6a9a2f9ae812d151ed621f72e99b1725 ]

    typo -- pkt_dev->nflows is for stats only, the number of concurrent
    flows is stored in cflows.
