2017-07-27igb: Explicitly select page 0 at initializationMatwey V Kornilov
commit 440aeca4b9858248d8f16d724d9fa87a4f65fa33 upstream. The functions igb_read_phy_reg_gs40g/igb_write_phy_reg_gs40g (which were removed in 2a3cdea) explicitly selected the required page at every phy_reg access. Currently, igb_get_phy_id_82575 relays on the fact that page 0 is already selected. The assumption is not fulfilled for my Lex 3I380CW motherboard with integrated dual i211 based gigabit ethernet. This leads to igb initialization failure and network interfaces are not working: igb: Intel(R) Gigabit Ethernet Network Driver - version 5.4.0-k igb: Copyright (c) 2007-2014 Intel Corporation. igb: probe of 0000:01:00.0 failed with error -2 igb: probe of 0000:02:00.0 failed with error -2 In order to fix it, we explicitly select page 0 before first access to phy registers.

2016-05-13igb: use BIT() macro or unsigned prefixJacob Keller
For bitshifts, we should make use of the BIT macro when possible, and ensure that other bitshifts are marked as unsigned. This helps prevent signed bitshift errors, and ensures similar style. Make use of GENMASK and the unsigned postfix where BIT() isn't appropriate. Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

2016-02-16igb: Add workaround for VLAN tag stripping on 82576Alexander Duyck
There was a workaround partially implemented for the 82576 that is needed in order for VLAN tag stripping to function correctly. The original code had side effects that would make it so the workaround was active on all MACs. I have updated the code so that the workaround is enabled, but limited to the 82576, or activated if we exceed the available unicast addresses. The workaround has a side effect of mirroring all of the traffic outgoing from the VFs back to the PF. As such it is not recommended to use the 82576 in promiscuous mode as it will take a performance hit, though this is now consistent with the performance as seen on the out-of-tree igb driver. I also limited the scope of the UTA bits all being set to only when the VMOLR register is enabled. This should limit the effects of the UTA register so that we don't pick up any excess traffic unless promiscuous mode has been enabled on the PF, whereas before the PF would have ended up in something equivalent to unicast promiscuous mode with VLAN filtering otherwise.

2015-12-14igb: Remove GS40G specific defines/functionsAaron Sierra
The I210 internal PHY can be accessed just as well with the access functions shared by 82580, I350, and I354 devices. A side effect of relying on the common functions, is that I210 cable length support is folded back into the common case which effectively reverts the following commit: commit 59f301046b276f87483b3afa3201a4273def06a9 Author: Carolyn Wyborny <carolyn.wyborny@intel.com> Date: Wed Oct 10 04:42:59 2012 +0000 igb: Update get cable length function for i210/i211 Cc: Carolyn Wyborny <carolyn.wyborny@intel.com> Signed-off-by: Aaron Sierra <asierra@xes-inc.com> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
