2017-02-03iwlwifi: mvm: cleanup incorrect and redundant defineSara Sharon
Currently we have up to 3 phy contexts - defined by NUM_PHY_CTX. However - some code paths validate the ID by using MAX_PHYS define which is set to 4. While there is no harm it is incorrect - since the maximum is 3. Remove the define and use the correct one. Cleanup the code a bit while at it.

2017-02-03iwlwifi: mvm: support unification of INIT and RT imagesSara Sharon
For a000 devices the INIT and RT images are unified to one image. The changes in the flow are the following: * Driver load only RT firmware - meaning that the nvm access command will be done in the RT image load flow. * A new command (NVM_ACCESS_COMPLETE) now signals to the FW that the driver is done accessing the NVM and FW can proceed with phy calibrations. * Phy DB is no longer sent from INIT FW to be restored by driver for the RT FW - all the phy DB is now internal to the FW. INIT complete will now follow the NVM access command, without phy DB calls before. * Paging command is sent earlier in the flow before NVM access to enable a complete load of FW. * caution must be care when restart is called since we may have not completed init flow even though we are in RT firmware.

2017-02-02i40e: add interrupt rate limit verbosityAlan Brady
Due to the resolution of the register controlling interrupt rate limiting, setting certain values for the interrupt rate limit make it appear as though the limiting is not completely accurate. The problem is that the interrupt rate limit is getting rounded down to the nearest multiple of 4. This patch fixes the problem by adding some feedback to the user as to the actual interrupt rate limit being used when it differs from the requested limit. Without this patch setting interrupt rate limits may appear to behave inaccurately.

2017-02-02i40e: refactor macro INTRL_USEC_TO_REGAlan Brady
This patch refactors the macro INTRL_USEC_TO_REG into a static inline function and fixes a couple subtle bugs caused by the macro. This patch fixes a bug which was caused by passing a bad register value to the firmware. If enabling interrupt rate limiting, a non-zero value for the rate limit must be used. Otherwise the firmware sets the interrupt rate limit to the maximum value. Due to the limited resolution of the register, attempting to set a value of 1, 2, or 3 would be rounded down to 0 and limiting was left enabled, causing unexpected behavior. This patch also fixes a possible bug in which using the macro itself can introduce unintended side-affects because the macro argument is used more than once in the macro definition (e.g. a variable post-increment argument would perform a double increment on the variable). Without this patch, attempting to set interrupt rate limits of 1, 2, or 3 results in unexpected behavior and future use of this macro could cause subtle bugs.

2017-02-02i40e: remove unnecessary __packedTushar Dave
'struct i40e_dma_mem' defined with 'packed' directive causing kernel unaligned errors on sparc. e.g. i40e: Intel(R) Ethernet Connection XL710 Network Driver - version 1.6.16-k i40e: Copyright (c) 2013 - 2014 Intel Corporation. Kernel unaligned access at TPC[44894c] dma_4v_alloc_coherent+0x1ac/0x300 Kernel unaligned access at TPC[44894c] dma_4v_alloc_coherent+0x1ac/0x300 Kernel unaligned access at TPC[44894c] dma_4v_alloc_coherent+0x1ac/0x300 Kernel unaligned access at TPC[44894c] dma_4v_alloc_coherent+0x1ac/0x300 Kernel unaligned access at TPC[44894c] dma_4v_alloc_coherent+0x1ac/0x300 i40e 0000:03:00.0: fw 5.1.40981 api 1.5 nvm 5.04 0x80002548 0.0.0 This can be fixed with get_unaligned/put_unaligned(). However no reference in driver shows that 'struct i40e_dma_mem' directly shoved into NIC hardware. But instead fields of the struct are being read and used for hardware. Therefore, __packed is unnecessary for 'struct i40e_dma_mem'. In addition, although 'struct i40e_virt_mem' doesn't cause any unaligned access, keeping it packed is unnecessary as well because of aforementioned reason. This change make 'struct i40e_dma_mem' and 'struct i40e_virt_mem' unpacked.

2017-02-02i40e: when adding or removing MAC filters, correctly handle VLANsJacob Keller
Instead of using i40e_add_filter or i40e_del_filter directly, when adding a MAC address, we should normally be using i40e_add_mac_filter or i40e_del_mac_filter. These functions correctly handle the various cases of VLAN mode or PVID settings. This ensures consistency and avoids the issues that can occur with the recent addition of a WARN_ON() in i40e_sync_vsi_filters.

Rename them so that their intent is clear. They function correctly regardless of whether we have any active VLANs or only have I40E_VLAN_ANY filters. The new names convey how they function in a more clear manner.

2017-02-02i40e: no need to check is_vsi_in_vlan before calling i40e_del_mac_all_vlanJacob Keller
This function won't be appreciably slower when in VLAN mode, so there is no real reason to not just call it directly. In either case, we still must search the full table for a MAC/VLAN pair. We do get to stop searching a tiny bit early in the case of knowing we are not in VLAN mode, but this is a minor savings and we can avoid the code complexity by not having to worry about the check.

2017-02-02i40e: don't allow i40e_vsi_(add|kill)_vlan to operate when VID<1Jacob Keller
Now that we have the separate i40e_(add|rm)_vlan_all_mac functions, we should not be using the i40e_vsi_kill_vlan or i40e_vsi_add_vlan functions when PVID is set or when VID is less than 1. This allows us to remove some checks in i40e_vsi_add_vlan and ensures that callers which need to handle VID=0 or VID=-1 don't accidentally invoke the VLAN mode handling used to convert filters when entering VLAN mode. We also update the functions to take u16 instead of s16 as well since they no longer expect to be called with VID=I40E_VLAN_ANY.

2017-02-02xgene_enet: remove bogus forward declarationsArnd Bergmann
The device match tables for both the xgene_enet driver and its phy driver have forward declarations that declare an array without a length, leading to a clang warning when they are not followed by an actual defitinition: drivers/net/ethernet/apm/xgene/../../../phy/mdio-xgene.h:135:34: warning: tentative array definition assumed to have one element drivers/net/ethernet/apm/xgene/xgene_enet_main.c:33:36: warning: tentative array definition assumed to have one element The declarations for the mdio driver are even in a header file, so they cause duplicate definitions of the tables for each file that includes them. This removes all four forward declarations and moves the actual definitions up a little, so they are in front of their first user. For the OF match tables, this means having to remove the #ifdef around them, and passing the actual structure into of_match_device(). This has no effect on the generated object code though, as the of_match_device function has an empty stub that does not evaluate its argument, and the symbol gets dropped either way.

2017-02-01net: phy: broadcom: rehook BCM54612E specific initRafał Miłecki
This extra BCM54612E code in PHY driver isn't really aneg specific. Even without it aneg works OK but the problem is no packets pass through PHY. Moreover putting this code inside config_aneg callback didn't allow resuming PHY correctly. When driver called phy_stop and phy_start it was putting PHY machine into RESUMING state. After that machine was switching into AN and NOLINK without ever calling phy_start_aneg. This prevented this extra setup from being called and PHY didn't work. This change has been verified to fix network on BCM47186B0 SoC device with BCM54612E.

2017-02-01be2net: fix initial MAC settingIvan Vecera
Recent commit 34393529163a ("be2net: fix MAC addr setting on privileged BE3 VFs") allows privileged BE3 VFs to set its MAC address during initialization. Although the initial MAC for such VFs is already programmed by parent PF the subsequent setting performed by VF is OK, but in certain cases (after fresh boot) this command in VF can fail. The MAC should be initialized only when: 1) no MAC is programmed (always except BE3 VFs during first init) 2) programmed MAC is different from requested (e.g. MAC is set when interface is down). In this case the initial MAC programmed by PF needs to be deleted. The adapter->dev_mac contains MAC address currently programmed in HW so it should be zeroed when the MAC is deleted from HW and should not be filled when MAC is set when interface is down in be_mac_addr_set() as no programming is performed in this case. Example of failure without the fix (immediately after fresh boot): # ip link set eth0 up <- eth0 is BE3 PF be2net 0000:01:00.0 eth0: Link is Up # echo 1 > /sys/class/net/eth0/device/sriov_numvfs <- Create 1 VF ... be2net 0000:01:04.0: Emulex OneConnect(be3): VF port 0 # ip link set eth8 up <- eth8 is created privileged VF be2net 0000:01:04.0: opcode 59-1 failed:status 1-76 RTNETLINK answers: Input/output error # echo 0 > /sys/class/net/eth0/device/sriov_numvfs <- Delete VF iommu: Removing device 0000:01:04.0 from group 33 ... # echo 1 > /sys/class/net/eth0/device/sriov_numvfs <- Create it again iommu: Removing device 0000:01:04.0 from group 33 ... # ip link set eth8 up be2net 0000:01:04.0 eth8: Link is Up Initialization is now OK. v2 - Corrected the comment and condition check suggested by Suresh & Harsha Fixes: 34393529163a ("be2net: fix MAC addr setting on privileged BE3 VFs") Cc: Sathya Perla <sathya.perla@broadcom.com> Cc: Ajit Khaparde <ajit.khaparde@broadcom.com> Cc: Sriharsha Basavapatna <sriharsha.basavapatna@broadcom.com> Cc: Somnath Kotur <somnath.kotur@broadcom.com> Signed-off-by: Ivan Vecera <cera@cera.cz> Acked-by: Sriharsha Basavapatna <sriharsha.basavapatna@broadcom.com> Signed-off-by: David S.

So far were were allocating struct bgmac in 3 places: platform code, bcma code and shared bgmac_enet_probe function. The reason for this was bgmac_enet_probe: 1) Requiring early-filled struct bgmac 2) Calling alloc_etherdev on its own in order to use netdev_priv later This solution got few drawbacks: 1) Was duplicating allocating code 2) Required copying early-filled struct 3) Resulted in platform/bcma code having access only to unused struct Solve this situation by simply extracting some probe code into the new bgmac_alloc function.
