igb: do not re-init SR-IOV during probe
During driver probing the following code path is triggered. igb_probe ->igb_sw_init ->igb_probe_vfs ->igb_pci_enable_sriov ->igb_sriov_reinit Doing the SR-IOV re-init is not necessary during probing since we're starting from scratch. Here we can call igb_enable_sriov() right away. Running igb_sriov_reinit() during igb_probe() also seems to cause occasional packet loss on some onboard 82576 NICs. Reproduced on Dell and HP servers with onboard 82576 NICs. Example: Intel Corporation 82576 Gigabit Network Connection [8086:10c9] (rev 01) Subsystem: Dell Device [1028:0481] Signed-off-by: Stefan Assmann <sassmann@kpanic.de> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
