[dpdk-dev] [RFC] net/ice: enable package download and RSS

[Qi Zhang <qi.z.zhang@intel.com>]

This is RFC for customer early eveluation.
It depends on below patch set
http://patchwork.dpdk.org/project/dpdk/list/?series=3189

package download mechanism is hard coded as:
A file named "ice_os_default.pkg" at current directory will be downloaded
by driver during init stage.

Also RSS is enable for UPD/TCP/SCTP+IPV4/IPV6 flows.
