[dpdk-dev] [PATCH] net/mlx5: fix calculation of offload flags on vectorized Rx

[Yongseok Koh <yskoh@mellanox.com>]

The pinfo variable has wrong data. This has to have merged data of two
fields from Rx completion - pkt_info and hdr_type_etc.

Fixes: 6cb559d67b83 ("net/mlx5: add vectorized Rx/Tx burst for x86")
