From: Tim Mann Date: Thu, 14 Jun 2007 20:16:38 +0000 (-0700) Subject: forcedeth: use unicast receive mode for WoL X-Git-Tag: v2.6.22-rc6~52 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2cc49a5ca14348f225beb888ad383064f2a96876;p=linux-2.6 forcedeth: use unicast receive mode for WoL I happened to notice that a system with an NVidia NIC using the forcedeth driver won't wake-on-LAN if the interface was in promiscuous mode when you power off. By experiment, it looks like the hardware needs to have NvRegPacketFilterFlags set to NVREG_PFF_ALWAYS|NVREG_PFF_MYADDR (i.e., receive unicast packets to my address) in order for WoL to work.
