Subject: net/netvsc: support multicast/promiscuous settings on VF
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=7d146e1769cc375d9410ee117a4c05fe6de11fa0;p=dpdk.git

net/netvsc: support multicast/promiscuous settings on VF

Provide API's to enable allmulticast and promiscuous in Netvsc PMD
with VF. This keeps the VF and PV path in sync.
