Summary: net/i40e Tx prepare unexpectedly rejects packet with
tunnel type set and no offloads requested
Product: DPDK
Version: 22.11
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: ethdev

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 information
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 packet
is rejected by Tx prepare. Requested Tx offload can be found in line 31 [4]
