From: Shahed Shaikh <shahed.sha...@cavium.com>
Tunneling offloads are represented by multi-bit values. So, feature
wise tunneling offload can only be entirely supported/unsupported
using PKT_TX_TUNNEL_MASK. Its upon PMDs to further isolate which of
the tunneling offload types are supported by respective PMD.
Using subset of bits from PKT_TX_TUNNEL_MASK to indicate supported vs
unsupported offloads can lead to undesired result.
Use PKT_TX_TUNNEL_MASK in QEDE_TX_OFFLOAD_MASK and use independent
value of supported PKT_TX_TUNNEL_* in .tx_pkt_prepare() to mark
supported tunnel offloads.
