From: Bruce Allan Date: Wed, 13 Jan 2010 02:05:18 +0000 (+0000) Subject: e1000e: provide MAC-family-specific function to set LAN ID X-Git-Tag: v2.6.34-rc1~233^2~595 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f4d2dd4cd4d001f5dc20fc76c780c0c20c000c23;p=profile%2Fivi%2Fkernel-x86-ivi.git e1000e: provide MAC-family-specific function to set LAN ID Provide MAC-specific function pointer to determine the LAN ID (PCI func). The LAN ID is used internally by the driver to determine which h/w lock to use to protect accessing the PHY on ESB2 as well as help to determine the alternate MAC address on some parts.
