[dpdk-dev] [PATCH v2 13/30] i40e/base: set shared bit for multicast filters

[Helin Zhang <helin.zhang@intel.com>]

Add the use of the new Shared MAC filter bit for multicast
and broadcast filters in order to make better use of the
filters available from the device. The FW folks have assured
that setting this bit on older FW will have no affect, so it
doesn't need a version check.
