Date: Mon, 20 Oct 2014 15:11:15 -0700 From: fruggeri@...stanetworks.com (Francesco Ruggeri) To: netdev@...r.kernel.org Cc: linux-kernel@...r.kernel.org, davem@...emloft.net, pv-drivers@...are.com, linux.nics@...el.com, fruggeri@...sta.com, e1000-devel@...ts.sourceforge.net Subject: [PATCH 1/1] e1000: unset IFF_UNICAST_FLT on WMware 82545EM VMWare's e1000 implementation does not seem to support unicast filtering. This can be observed by configuring a macvlan interface on eth0 in a VM in VMWare Fusion 5.0.5, and trying to use that interface instead of eth0. Tested on 3.16.
