[dpdk-stable] [PATCH] net/ixgbe: fix tunnel id format error for FDIR

[Wei Zhao]

In cloud mode for FDIR, tunnel id should be set as protocol
request, the lower 8 bits should be set as reserved.

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