[ovs-dev] [PATCH] netdev-dpdk: Silence DPDK Wbad-function-cast warning

[John McNamara]

This patch turns off the Wbad-function-cast warning locally in netdev-dpdk.c.
This warning is output 50+ times during compilation with the --with-dpdk
config option.

The warning is generated by including DPDK's rte_common.h header file.
It is a valid warning but applies to a function that isn't used in OVS.
