[dpdk-dev] [PATCH 2/2] net/mlx5: fix L4 packet type support
Yongseok Koh
yskoh at mellanox.com
Wed Jul 26 21:29:33 CEST 2017
TCP/UDP/NONFRAG/FRAG flags aren't counted for both outer and inner header
even though device supports it.
Fixes: 0603df73a077 ("net/mlx5: fix Rx packet validation and type")
Fixes: 6cb559d67b83 ("net/mlx5: add vectorized Rx/Tx burst for x86")
