[dpdk-dev] Is Flow Director supported on the x540 chipset?

Hi Fulvio,

I have been checked few information about the datasheet of the X540 card.
The X540 card is a derivative of the 82599. It's very similar to the 82599 card.

The both cards use the same hardware registers for the flow director.
Thus, the current code of the dpdk for the flow director should work
with X540 card too.

I think you only need to change few lines in lib/librte_pmd_ixgbe/ixgbe_fdir.c:

  - if (hw->mac.type != ixgbe_mac_82599EB)
  + if (hw->mac.type != ixgbe_mac_82599EB || hw->mac.type != ixgbe_mac_X540)

Let me know if you can test it and please provide a patch if it works.

Thanks. Regards,

Maxime
