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. Miller <davem@davemloft.net>

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:

On the Northstar SoC (BCM4707 and BCM53018) we have to enable all GMAC cores when we just want to use on. We iterate over all the cores and activate them. Signed-off-by:

This function is used to get a specific core when there is more than one core of that specific type. This is used in bgmac to reset all GMAC cores. 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: -

phy_scan_fixups() isn't and shouldn't be called by the drivers directly, so unexport it. And since Florian Fainelli's recent patches, the function is only called locally, so we can make it static as well. Signed-off-by:

If the user does not assign a VF MAC address, then just report it as zero. Attempting to guess the correct primary MAC address of the VF is a futile and heartbreaking endeavour. Change-Id: I2673577a160afb6fc55094c890467b44e60c7584 Signed-off-by:

Don't complain when we disable queues that are already disable, or enable them when they're already enabled. This removes a bunch of bogus log messages that we see at every VF reset. Change-Id: Ia127be572abdccc48a53d8c43f8a07b8bb920de1 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.

The HMC error interrupt would generate an un-necessary message "unhandled interrupt", causing extra log spam, in addition to causing a reset that was not necessary. Prevent this issue by handling the HMC error case explicitly, and only reset if the interrupt was from some of the other causes. Change-Id: Iabd203ba1dfc26a136b638597f3e9991acfa29f3 Signed-off-by:

Scott Feldman says: ==================== bonding: final set of netlink patches v2: - per Jiri's comment, fix ad_select checking against parm table by spliting bond_parse_parm() into several funcs. Go ahead and apply same technique to all parameters using parm table. - fix netlink msg size to including missing nest attr - drop the last patch for active_slaves. This patch needs to be reworked per Jiri's comments and shouldn't hold up finalizing the conversion of the existing parameter to netlink attributes. Ding, assuming this patch set goes in, you should have all you need to start converting module parameter setting/checking over to funcs in *_options.c. I'll send iproute2 patch for bonding netlink support once this patch set is accepted. v1: The following series implements the last set of bonding netlink attributes for 802.3ad mode: lacp_rate ad_select ad_info, nest of: ad_aggregator ad_num_ports ad_actor_key ad_partner_key ad_partner_mac The last patch adds an additional netlink attribute, active_slaves, which is a nested list of ifindices for current active slaves. We're using this list to enable/disable hashing of ports in a hardware LAG implementation. In the same way bonding driver includes/excludes ports for 802.3ad egress hashing, hardware ports are included/excluded from egress hashing by hardware based on port active status. Yes, data path offloaded to hardware, control path remains in kernel via bonding driver. ==================== Signed-off-by: -
