From 6f7f8aa69acb391ba98f5186ca09434d9d0f52ee Mon Sep 17 00:00:00 2001 From: Shradha Shah Date: Wed, 6 May 2015 01:00:07 +0100 Subject: [PATCH] sfc: Bind the sfc driver to any available VF's Add the device ID of the VF to the PCI device ID table. Added a boolean flag is_vf in efx_nic_type to differentiate between a VF and PF at probe time. This flag is useful in later patches while setting MAC address specially in the PCI-passthrough case.
