            Bug ID: 1134
           Summary: net/i40e Tx prepare unexpectedly rejects packet with
                    tunnel type set and no offloads requested

net/i40e Tx prepare unexpectedly rejects packet with tunnel type set and no
offloads requested

Tunnel type (e.g. RTE_MBUF_F_TX_TUNNEL_VXLAN) is just an auxiliary informat=
ion
which does not request any Tx offload itself (similar to RTE_MBUF_F_TX_IPV4=
).
So, if a packet has the tunnel type set it should not be rejected by
i40e_simple_prep_pkts() as unsupported offload requested. I.e.
RTE_MBUF_F_TX_TUNNEL_MASK should be included in
I40E_TX_OFFLOAD_SIMPLE_SUP_MASK.

Found using [1]. Line 48 [2] sets ol_flags. Line 79 [3] shows that the pack=
et
is rejected by Tx prepare.  Requested Tx offload can be found in line 31 [4]
