[dpdk-dev] [PATCH v2 1/5] mbuf: fix bitmask of Tx offload flags

[Jingjing Wu <jingjing.wu@intel.com>]

Some Tx offload flags are missed in bitmask of all supported packet
Tx offload features flags.
This patch fixes it by redefining PKT_TX_OFFLOAD_MASK.
PKT_RX_OFFLOAD_MASK is also defined in this patch.
