Subject: [PATCH 4.4 277/312] net: ethernet: mvneta: Remove IFF_UNICAST_FLT which is not implemented

From: Andrew Lunn <andrew@...n.ch>

commit 97db8afa2ab919fc400fe982f5054060868bdf07 upstream.

The mvneta driver advertises it supports IFF_UNICAST_FLT. However, it
actually does not. The hardware probably does support it, but there is
no code to configure the filter. As a quick and simple fix, remove the
flag. This will cause the core to fall back to promiscuous mode.
