When disabling and enabling VFs on a live system with the VF driver loaded, it's possible to receive an admin queue message from the VF driver at an inconvenient time, e.g. when the associated data structures aren't present or configured. This causes a rather inconvenient panic. To guard against this, we change the order of when we set num_alloc_vfs when turning off SR-IOV, and then gate processing of any VF messages based upon that value. Likewise, when enabling VFs, we shut off the relevant interrupt until configuration is complete. Change-Id: I0c172c056616c2bebd78bbc807ab446eb484deea Signed-off-by:

Earlier we were reading Shadow RAM (copy of the NVM) which can differ from the actual NVM. Use AQ instead to read the actual NVM. Change-Id: Ia0f2773b722db77d093f738c068af872be69bbd4 Signed-off-by:

bgmac: add initial support for core rev 4 on ARM BCM47xx ==================== This adds support for core rev 4 and ARM BCM47XX. With an other fix to the platform code I am now getting over 200 MBit/s with this Ethernet driver, the DMA problems are solved are unrelated to bgmac. v3: - moved flags calculation for bcma_core_enable() into if block - remove hard coding of phy address to BGMAC_PHY_NOREGS v2: add changed suggested by Rafał ==================== Signed-off-by:David S.

This adds support for the Northstar SoC. This SoC does not have a PMU in bcma and no register on it should be called. In addition it support 2.5 GBit/s Ethernet to the PHY. This GMAC core is not fully working there are still problems with the DMA controller. Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates This series contains updates to i40e and pci_regs.h. Anjali provides a patch to prevent messages from stray HMC events, except at interrupt message level, and refactors the HMC error handling. Catherine adds routines in probe to populate/check PCI bus speed and width, then verify we are in a 8GT/s x8 PCIe slot and warn when we are not. Shannon adds Wake-on-LAN support for i40e, fixes curly brace use as well as return type for i40e_vsi_clear_rings(). Joseph implements receive offload for VXLAN for i40e, where the hardware supports checksum offload/verification of the inner/outer header. Mitch provides the bulk of the changes, where he refactors the VF reset code so that it works on real hardware. Then does code cleanup by calling existing functions to enable and disable queues for VFs and remove unused functions. Removes a unnecessary log messages that are seen at every VF reset, for example complaining about disabling queues that are already disabled. Fixes an error return when the VF asks to add an invalid MAC address and if the VF sends a bad message, make it more informative about what is actually going on. Jesse refactors the LED function to flash LED lights correctly. v2: - removed patch 5 "i40e: add set settings and pauseparam" based on feedback from Ben Hutchings, will re-work that patch for later submission - Added patch "i40e: Implementation of vxlan ndo's" from Joseph to address Or Gerlitz's questions and concerns. This patch adds the implementation for the VXLAN ndo's and allows the hardware to do receive checksum offload for inner packets on the UDP ports that VXLAN notifies us about. - Added patch "i40e: using for_each_set_bit to simplify the code" from Wei Yongjun. This patch uses for_each_set_bit() to simply the code. v3: - fixed indentation issue in patch 11 based on feedback from Sergei Shtylyov. Sorry for the delayed release of v4, it was delayed to the holidays. v4: - Addressed Or Gerlitz's concerns about trying to get a hold of a mutex while holding a spin lock in patch 6 by executing the AQ commands from a subtask. - Addressed David Miller's Kconfig concerns by creating a Kconfig VXLAN option for i40e and wrapped appropriate code with the config option in patch 6. - Updated patch 7 based on the changes made in patch 6 in the above two bullets. v5: - Added the patch to pci_regs.h based on David Miller's feedback to add PCI defines for speed and width - Updated patch 3 description to better explain the changes based on feedback from David Miller - Updated patch 4 to use the newly added defines to pci_regs.h instead of local defines - Updated patch 7 to use <net/vxlan.h> in the #include based on feedback from David Miller ==================== Signed-off-by: -

Fix the VF reset flow so that it works on real hardware. After discussions with the HW team, the reset flow has been changed somewhat. - Change the i40e_reset_vf function to a void type, and fix up the callers to reflect this. - Move the MSI-X disable code to i40e_free_vf_res since it must be done every time the VF is freed, regardless of whether or not it is reset. - Ensure that the PCIe bus is quiet before polling the reset bit. - Don't clear the VFGEN_RSTAT1 register at the beginning as it is cleared by the reset. - Poll longer for the reset to be done. - Disable the queues using an existing function rather than rolling our own. - Free and reallocate the VSI after reset to avoid rx hang.

The VF reset code will be refactored in future patches. Part of that refactor required it to call i40e_alloc_vf_res and i40e_free_vf_res, so the function must be moved. In order to make the future patches more readable, we perform the function move here, with no other changes. Change-Id: If6567c9c0bada6caafb2ee0227e0d9d50d05f27f Signed-off-by:

Wake on LAN is disabled by default and will remain that way for most platforms, but there is an NVM setting that allows vendors to enable it for a port if they think they've provided the right power environment for the device. This patch adds code to check the NVM setting and enable Magic Packet use if WoL is enabled for the port. Since only Magic Packet is supported, there's not a lot of HW configuration needed.
