Subject: [PATCH] net/ixgbe: fix tunnel type set error for FDIR

[ upstream commit 876b450ed99d2c96c5b71360cc84f7b0b8f506f4 ]

Tunnel type format should be translated to ixgbe required format
before register set in FDIR cloud mode, Ans also some register
not useful in cloud mode but only useful in IP mode should be set
to zero as datasheet request.

Fixes: 82fb702077f6 ("ixgbe: support new flow director modes for X550")
Fixes: 11777435c727 ("net/ixgbe: parse flow director filter")
