[dpdk-dev] [PATCH] net/i40e: fix broadcast promiscuous mode setting

[Wenzhuo Lu <wenzhuo.lu@intel.com>]

When setting up the VSIs, MAC filter is used for
receiving MAC broadcast packets.
We should follow it to implement the broadcast
promiscuous mode setting.

Fixes: 61fff9b4c68b (net/i40e: set VF broadcast mode from PF)
