Some code in the mlx4 IB driver stack assumed MLX4_MAX_PORTS ports. Instead, we should only loop until the number of actual ports in i the device, which is stored in dev->caps.num_ports. Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to e100, igb, igbvf, ixgbe and ixgbevf. Stefan adds a igb patch to enable the ability strip VLAN header information for packets bound for a VM on i350 hardware. Joe Perches provides patches for e100, igb, igbvf, ixgbe and ixgbevf to convert the use of __constant_<foo> to just <foo> to align with the rest of the kernel. Don provides two fixes for ixgbe, first resolves a link issue with DA cables where we were not always freeing the firmware/software semaphore after grabbing it. Second stops caching whether the management firmware was enabled, however since this is not static, we really need to verify with each check. Jacob provides six fixes/cleanups for ixgbe, most notably, correct the stop_mac_link_on d3() to check the Core Clock Disable bit before stopping link and to fully check to see if manage firmware is running or could be enabled before bringing down the link. Fix flow control auto-negation for KR/KX/K4 interfaces, since setting up MAC link, the cached autoc value and current autoc value were being incorrectly used to determine whether link reset is required. Emil provides a fix for ixgbe where there was a chance for aggressive start_ndo_zmit() callers to sneak packets between enabling the Tx queues and the link coming up. To resolve this, move the call to enable Tx queues to after the link is established. ==================== Signed-off-by: -

This patch moves the call to enable Tx queues after the link is established. Previously there was a chance for aggressive start_ndo_xmit() callers to sneak packets between enabling the Tx queues and the link coming up. In addition it replaces netif_tx_start_all_queues() with netif_tx_wake_all_queues() to allow for flushing of the qdisc. CC: Arun Sharma <asharma@fb.com> Signed-off-by:

This patch replaces some direct uses of pci_read_config_word with the protected ixgbe_read_pci_cfg_word function, which checks for whether the adapter is removed when LER is enabled. We shouldn't use the pci_read_config_word calls directly because of these checks. This patch also cleans up an unnecessary save of a pointer to the mac object, as our standard style is to just use the hw pointer. CC: Arun Sharma <asharma@fb.com> Signed-off-by:

This patch reverts the addition of the fiber_fixed type, which ended up never being used. We don't have plans to support this type going forward, and there is no reason to keep an unused type around polluting the code.

This patch fixes flow control autonegotiation for KR/KX/K4 interfaces. When setting up MAC link, the cached autoc value and current autoc value were being incorrectly used to determine whether link reset is required. This resulted in the driver ignoring and discarding flow control negotiation changes that occur since the caching happened, as well as when the mac was being setup. This patch also splits the assignments for the 3 autoc variables into their own block, and adds a comment explaining what each one means, in order to help keep logic more straightforward while reading the code.

Previously, we did a full check to see if MNG FW was running. Instead, we should only check to see whether it could be enabled. Since it may become active while down, we don't want to bring the link down. CC: Arun Sharma <asharma@fb.com> Signed-off-by:

For i350 VLAN stripping for VMs is not enabled in the VMOLR register but in the DVMOLR register. Making the changes accordingly. It's not necessary to unset the E1000_VMOLR_STRVLAN bit on i350 as the hardware will simply ignore it. Without this change if a VLAN is configured for a VF assigned to a guest via (i.e.) ip link set p1p1 vf 0 vlan 10 the VLAN tag will not be stripped from packets going into the VM. Which they should be because the VM itself is not aware of the VLAN at all. Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to i40e, i40evf, e1000e, ixgbe and ixgbevf. Mitch adds support for the VF link state ndo which allows the PF driver to control the virtual link state of the VF devices. Added support for viewing and modifying RSS hash options and RSS hash look-up table programming through ethtool for i40evf. Fixed complaint about the use of min() where min_t() should be used in i40evf. Anjali adds support for ethtool -k option for NTUPLE control for i40e. Elizabeth cleans up and refactors i40e_open() to separate out the VSI code into its own i40e_vsi_open(). Jesse enables the hardware feature head write back to avoid updating the descriptor ring by marking each descriptor with a DD bit and instead writes a memory location with an update to where the driver should clean up to in i40e and i40evf. Reduces context descriptors for i40e/i40evf since we do not need context descriptors for every packet, only for TSO or timesync. Dan Carpenter fixes a potential array underflow in i40e_vc_process_vf_msg(). Dave fixes an e1000e hardware unit hang where the check for pending Tx work when link is lost was mistakenly moved to be done only when link is first detected to be lost. Fixed a problem with poor network performance on certain silicon in e1000e when configured for 100M HDX performance. Carolyn adds register defines needed for time sync functions and the code to call the updated defines. Jacob adds the ixgbe function for writing PCI config word and checks whether the adapter has been removed first. Mark adds the bit __IXGBEVF_REMOVING to indicate that the module is being removed because the __IXGBEVF_DOWN bit had been overloaded for this purpose, but leads to trouble. ixgbevf_down function can now prevent multiple executions by doing test_and_set_bit on __IXGBEVF_DOWN. v2: - dropped patch Mitch's patch "i40evf: Support RSS option in ethtool" based on feedback from Ben Hutchings so that Mitch can re-work the patch solution v3: - removed unnecessary parenthesis in patch 1 based on feedback from David Miller - changed a macro to get the next queue to a function in patch 2 based on feedback from David Miller - added blank lines after variable declaration and code in two functions in patch 6 based on feedback from David Miller ==================== Signed-off-by: -

The ixgbevf_down function can now prevent multiple executions by doing test_and_set_bit on __IXGBEVF_DOWN. This did not work before introduction of the __IXGBEVF_REMOVING bit, because of overloading of __IXGBEVF_DOWN. Also add smp_mb__before_clear_bit call before clearing the __IXGBEVF_DOWN bit.

The check for pending Tx work when link is lost was mistakenly moved to be done only when link is first detected to be lost. It turns out there is a small window of opportunity for additional Tx work to get queued up shortly after link is dropped. Move the check back to the place it was before in the watchdog task. Put in additional debug information for other reset paths and a final catch-all for false hangs in the scheduled function that prints out the hardware hang message. Signed-off-by:

If "vf_id" is smaller than hw->func_caps.vf_base_id then it leads to an array underflow of the pf->vf[] array. This is unlikely to happen unless the hardware is bad, but it's a small change and it silences a static checker warning. Fixes: 7efa84b7 ('i40e: support VFs on PFs other than 0') Signed-off-by:

The HLUT programming loop in in i40evf_configure_rss was a) overly- complicated, and b) just plain broken. Most of the entries ended up being not written at all, so most of the flows ended up at queue zero. Refactor the HLUT programming loop to simply walk through the registers and write four values to each one, incrementing through the number of available queues.

This netdev op allows the PF driver to control the virtual link state of the VF devices. This can be used to deny naughty VF drivers access to the wire, or to allow VFs (regardless of temperament) to communicate with each other over the device's internal switch even though external link is down. Add the actual ndo function, and modify vc_notify_link_state to check the link status of each VF before sending a message in the case when physical link changes state.
