[dpdk-dev] [PATCH v2] net/i40e: fix parsing tunnel filter issue

[Beilei Xing]

VNI of VXLAN is parsed wrongly. The root cause is that
array vni in item VXLAN also uses network byte ordering.

Fixes: d416530e6358 ("net/i40e: parse tunnel filter")

v2 changes:
 Use rte_be_to_cpu_32 api instead of the new function.
