Laurent Pinchart says: ==================== sh_eth: Fix the race between open and MDIO bus registration This patch series fixes the race condition that exists in the sh_eth driver between network device open and MDIO bus registration. The actual fix is in patch 4/5, with previous patches preparing the driver and patch 5/5 cleaning up an unrelated issue. I've based the idea on Sergei's attempt to fix the problem and can successfully boot the Koelsch board over NFS with this series. I might have missed other issues though, hence the RFC status. The patches are based on top of the latest net-next master branch. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

"goto" is well accepted for error paths in the kernel but should not be used unnecessarily. Return the correct value directly instead of using a goto when possible.

Network API functions that rely on the MDIO bus can be called as soon as the driver calls register_netdev(). Register the MDIO bus before the network device to avoid race conditions.

The MDIO bus parent is set to the network device. Beside not reflecting the hardware topology, this prevents registering the MDIO bus before initializing the network device. Fix it by setting the MDIO bus parent to the platform device.

Memory allocated for the MDIO bus with the devm_kzalloc() API is associated with the network device. While this will cause memory to be freed at the right time, it doesn't allow allocating memory before the network device is initialized. Replace the network device with the parent platform device for memory allocation to remove that dependency. This also improves consistency with the other devm_* calls in the driver that all use the platform device.

This makes the generic of_mdiobus_register parse the DT compatible string for the pattern ethernet-phy-idAAAA.BBBB. If present it should be a value that matches the phy-id register normally readable through MDIO. When the ID is given the phy autoprobing is defeated and the phy is created directly. This is necessary to support phy's that cannot be autoprobed when of_mdiobus_register is called. Specifically, my case has the phy in reset at of_mdiobus_register, the reset is only released once the ethernet driver starts, before it attaches to the phy.

Or Gerlitz says: ==================== mlx4: Add support for single port VFs The mlx4 Firmware && driver expose both ports of the device through one PCI function. This can be non-optimal under virtualization schemes where the admin would like the VF to expose one interface to the VM, etc. This series from Matan Barak adds support for single ported VFs. Since all the VF interaction with the firmware passes through the PF driver, we can emulate to the VF they have one port, and further create a set of the VFs which act on port1 of the device and another set which acts on port2.

A new syntax is added for the module parameters num_vfs and probe_vf. num_vfs=p1,p2,p1+p2 probe_bf=p1,p2,p1+p2 Where p1(2) is the number of VFs on / probed VFs for physical port1(2) and p1+p2 is the number of dual port VFs. Single port VFs are currently supported only when the link type for both ports of the device is Ethernet.

Adds support for N-Port VFs, this includes: 1. Adding support in the wrapped FW command In wrapped commands, we need to verify and convert the slave's port into the real physical port. Furthermore, when sending the response back to the slave, a reverse conversion should be made. 2. Adjusting sqpn for QP1 para-virtualization The slave assumes that sqpn is used for QP1 communication. If the slave is assigned to a port != (first port), we need to adjust the sqpn that will direct its QP1 packets into the correct endpoint. 3. Adjusting gid[5] to modify the port for raw ethernet In B0 steering, gid[5] contains the port. It needs to be adjusted into the physical port. 4. Adjusting number of ports in the query / ports caps in the FW commands When a slave queries the hardware, it needs to view only the physical ports it's assigned to. 5. Adjusting the sched_qp according to the port number The QP port is encoded in the sched_qp, thus in modify_qp we need to encode the correct port in sched_qp.

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: David S. Miller <davem@davemloft.net>

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.

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.

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.

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.
