Date: Tue, 17 Dec 2013 09:01:54 +0200 From: Amir Vadai <amirv@...lanox.com> To: "David S. Miller" <davem@...emloft.net> Cc: Or Gerlitz <ogerlitz@...lanox.com>, Yevgeny Petrilin <yevgenyp@...lanox.com>, Amir Vadai <amirv@...lanox.com>, netdev@...r.kernel.org, Hadar Hen Zion <hadarh@...lanox.com> Subject: [PATCH net-next V1 05/11] net/mlx4_en: Implement ndo_get_phys_port_id From: Hadar Hen Zion <hadarh@...lanox.com> Use the port GUID read from the firmware to identify the physical port. This port identifier is available via ndo_get_phys_port_id for both PF and VF net-devices.
