2018-09-22net: hns3: Fix speed/duplex information loss problem when executing ethtool ↵Fuyun Liang1-27/+39
ethx cmd of VF Our VF has not implemented the ops for get_port_type. So when we executing ethtool ethx cmd of VF, hns3_get_link_ksettings will return directly. And we can not query anything. To support get_link_ksettings for VF, this patch replaces get_port_type with get_media_type. If the media type is HNAE3_MEDIA_TYPE_NONE, hns3_get_link_ksettings will return link information of VF.

2018-09-22net: hns3: Fix tqp array traversal condition for vfJian Shen1-26/+24
There are two tqp_num variables "hdev->tqp_num" and "kinfo->tqp_num" used in VF. "hdev->tqp_num" is the total tqp number allocated to the VF, and "kinfo->tqp_num" indicates the tqp number being used by the VF. Usually the two variables are equal. But for the case hdev->tqp_num larger than rss_size_max, and num_tc is 1, "kinfo->tqp_num" will be less than "hdev->tqp_num". In original codes, "hdev->tqp_num" is always used to traverse the tqp array of kinfo. It may cause null pointer error when "hdev->tqp_num" is larger than "kinfo->tqp_num" Fixes: e2cb1dec9779 ("net: hns3: Add HNS3 VF HCL(Hardware Compatibility Layer) Support") Signed-off-by: Jian Shen <shenjian15@huawei.com> Signed-off-by: Peng Li <lipeng321@huawei.com> Signed-off-by: Salil Mehta <salil.mehta@huawei.com> Signed-off-by: David S.

The previous commit to ravb had the side effect of making the PHY advertise Pause and Asym Pause, which previously did not happen. By default, phydev->supported has both forms of pause enabled, but phydev->advertising does not. The new phy_remove_link_mode() copies phydev->supported to phydev->advertising after removing the requested link mode.

2018-09-20mlxsw: spectrum_buffers: Allow configuration of static poolsPetr Machata1-17/+33
Some pools configured through the sb_pm entries may have by default static size. The MC pool is now not explicitly configured, however it gets configured as static implicitly by 0-initializing sb->prs, and a follow-up patch adds an explicit configuration to the same effect. To support this, pass max_buff taken from sb_pm and sb_cm entries through cell conversion before handing it to mlxsw_sp_sb_pm_write(), if the pool that the sb_pm entry configures is statically-sized. To keep current behavior, update mlxsw_sp_sb_cms_egress[] to denote buffer sizes in bytes (assuming Spectrum 1 cell sizes, which the original code assumed as well) instead of cells. Note that a follow-up patch changes this to infinite size. Also tweak a comment at SBMM configuration to remain true now that statically-sized pools exist.

Currently, all sb_pm entries have 0 for min_buff, and therefore the actual unit is immaterial. However, in a follow-up patch we want to add entries with non-zero minimum.

The SBCM register configures the shared buffer configuration according to port and TC. So far all pools have had a dynamic size, where the infinite size is easy to express by using max_buff of 0xff. However the MC pool should be configured with static size, and the infinite size thus needs to be set using the field SBCM.infi_max. Therefore add the field infi_max to the SBCM register and to mlxsw_reg_sbcm_pack(). Extend mlxsw_sp_sb_cm_write() to handle infinite sizes as well.

2018-09-20mlxsw: spectrum_buffers: Use devlink pool indices throughoutPetr Machata1-205/+170
Currently, mlxsw assumes that each ingress pool has its egress counterpart, and that pool index for purposes of caching matches the index with which the hardware should be configured. As we want to expose the MC pool, both of these assumptions break. Instead, maintain the pool index as long as possible. Unify ingress and egress caches and use the pool index as cache index as well. Only translate to FW pool numbering when actually packing the registers. This simplifies things considerably, as the pool index is the only quantity necessary to uniquely identify a pool, and the pool/direction split is not necessary until firmware is talked to. To support the mapping between pool indices and pool numbers and directions, which is not neatly mathematical anymore, introduce a pool descriptor table, indexed by pool index, to facilitate the translation. Include the MC pool in the descriptor table as well, so that it can be referenced from mlxsw_sp_sb_cms_egress.

2018-09-20net: toshiba: remove a redundant local variable 'index_specified'zhong jiang1-6/+3
The local variable 'index_specified' is never used after being assigned. hence it should be redundant adn can be removed. Signed-off-by: zhong jiang <zhongjiang@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-09-20nfp: provide a better warning when ring allocation failsJakub Kicinski1-4/+12
NFP supports fairly enormous ring sizes (up to 256k descriptors). In commit 466271703867 ("nfp: use kvcalloc() to allocate SW buffer descriptor arrays") we have started using kvcalloc() functions to make sure the allocation of software state arrays doesn't hit the MAX_ORDER limit. Unfortunately, we can't use virtual mappings for the DMA region holding HW descriptors. In case this allocation fails instead of the generic (and fairly scary) warning/splat in the logs print a helpful message explaining what happened and suggesting how to fix it.

2018-09-20r8169: remove duplicated RTL8169s PHY initialization stepsHeiner Kallweit1-9/+0
Setting register 0x82 to value 01 is done a few lines before for all chip versions <= 06 anyway. And setting PHY register 0x0b to value 00 is done at the end of rtl8169s_hw_phy_config() already. So we can remove this. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2018-09-20r8169: simplify RTL8169 PHY initializationHeiner Kallweit1-5/+2
PCI_LATENCY_TIMER is ignored on PCIe, therefore we have to do this for the PCI chips (version <= 06) only. Also we can move setting PCI_CACHE_LINE_SIZE. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
