[Bad commit]
commit 264243ffe3d2fcc856cc0583de3220571d6f718f

    examples/ptpclient: fix delay request message

    [ upstream commit 21ba4d572a5cb404cd3d02a59aaf7997bb4e8a39 ]

    The size of delay request message sent out by the DPDK
    ptpclient application was observed to have extra length
    than expected. Due to this, bad messages were observed
    on the master side and delay response was not received.
    This patch fixes this bug.

    Fixes: ab129e9065a5 ("examples/ptpclient: add minimal PTP client")
