Subject: [PATCH net-next] hv_netvsc: Correct filter setting for multicast/broadcast
Date: Fri,  9 Mar 2018 14:25:23 +0100	[thread overview]
Message-ID: <1520601923-26931-1-git-send-email-mgamal@redhat.com> (raw)

Commit 009f766 intended to filter multicast/broadcast, however
the NDIS filter wasn't set properly in non-promiscuous modes,
which resulted in issues like DHCP timeouts.
This patch sets the filter flags correctly.

Fixes: 009f766 ("hv_netvsc: filter multicast/broadcast")
