workaround is to create a sriov,conf file in /etc/init .. example is as below

cat /etc/init/sriov.conf
description "SRIOV"

start on (starting networking)
stop on runlevel [016]
limit core unlimited unlimited
# For DPDK vRouter we need longer timeout to let KNI devices shut down
# gracefully
kill timeout 20

# Restart the process if it dies with a signal
# or exit code not given by the 'normal exit' stanza.
respawn

# Give up if restart occurs 10 times in 90 seconds.
respawn limit 10 90

pre-start script
    echo 7 > /sys/class/net/p1p1/device/sriov_numvfs
    echo 7 > /sys/class/net/p1p2/device/sriov_numvfs
end script

script
end script

post-start script
end script

pre-stop script
end script

post-stop script
end script
