[net-next 14/14] i40e: fix fdir programming

[Jeff Kirsher <jeffrey.t.kirsher@intel.com>]

From: Jesse Brandeburg <jesse.brandeburg@intel.com>

There were a couple of fields in the fdir descriptor setup that
were not being reprogrammed, which left the opportunity for stale
data to be pushed as part of the descriptor next time it was used.
