[dpdk-dev] [PATCH v2] net/i40e: fix offload flag checking in simple Tx datapath

[Alvin Zhang]

Tx offload flags 'PKT_TX_IPV6, PKT_TX_IPV4, PKT_TX_OUTER_IPV6,
PKT_TX_OUTER_IPV4' are supported in simple datapath.

This patch removes these offload flags from packet checking in simple
Tx datapath and defines 2 macro I40E_TX_OFFLOAD_SIMPLE_SUP_MASK
and I40E_TX_OFFLOAD_SIMPLE_NOTSUP_MASK.

Fixes: 146ffa81d05e ("net/i40e: add Tx preparation for simple Tx datapath")
