Message-Id: <1414672436-20616-2-git-send-email-jeffrey.t.kirsher@intel.com> Date: Thu, 30 Oct 2014 05:33:53 -0700 From: Jeff Kirsher <jeffrey.t.kirsher@...el.com> To: davem@...emloft.net Cc: Francesco Ruggeri <fruggeri@...stanetworks.com>, netdev@...r.kernel.org, nhorman@...hat.com, sassmann@...hat.com, jogreene@...hat.com, Francesco Ruggeri <fruggeri@...sta.com>, Jeff Kirsher <jeffrey.t.kirsher@...el.com> Subject: [net 1/4] e1000: unset IFF_UNICAST_FLT on WMware 82545EM From: Francesco Ruggeri <fruggeri@...stanetworks.com> 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.
