[dpdk-dev] [PATCH 1/4] net/i40e: support replace filter type

[Beilei Xing <beilei.xing@intel.com>]

Add new admin queue function and extended fields
in DCR 288:
 - Add admin queue function for Replace filter
   command (Opcode: 0x025F)
 - Add General fields for Add/Remove Cloud filters
   command

This patch will be removed to base driver in future.
