[dpdk-dev] [PATCH v3] gso: fix VxLAN/GRE tunnel checks

[Andrew Rybchenko]

Tunnel type is an enum in PKT_TX_TUNNEL_MASK bits.
As the result, for example, IPIP or MPLSinUDP tunnel packets may be
incorrectly treated internally as VXLAN.

Fixes: b058d92ea95d ("gso: support VxLAN GSO")
Fixes: 70e737e448c7 ("gso: support GRE GSO")
