[ovs-dev] [patch_v5] dp-packet: Reset DPDK HWOL checksum flags on init.

[Darrell Ball]

Reset the DPDK HWOL checksum flags in dp_packet_init_.
The new HWOL bad checksum flag is uninitialized for non-dpdk ports and
this is noticed as test failures using netdev-dummy ports, when built with
the --with-dpdk flag set. Hence, in this case, packets may be marked as
having a bad checksum.

Fixes: 7451af618e0d ("dp-packet : Update DPDK rx checksum validation functions.")

v3->v5: Update the commit message with more context.

v2->v3: Use existed API to reset both the DPDK HWOL flags.

v1->v2: Fix build failure for without --with-dpdk.
