Jiri Pirko says: ==================== bonding/team offload + mlxsw implementation This patchset introduces needed infrastructure for link aggregation offload - for both team and bonding. It also implements the offload in mlxsw driver. Particulary, this patchset introduces possibility for upper driver (bond/team/bridge/..) to pass type-specific info down to notifier listeners. Info is passed along with NETDEV_CHANGEUPPER/NETDEV_PRECHANGEUPPER notifiers. Listeners (drivers of netdevs being enslaved) can react accordingly. Other extension is for run-time use. This patchset introduces new netdev notifier type - NETDEV_CHANGELOWERSTATE. Along with this notification, the upper driver (bond/team/bridge/..) can pass some information about lower device change, particulary link-up and TX-enabled states. Listeners (drivers of netdevs being enslaved) can react accordingly. The last part of the patchset is implementation of LAG offload in mlxsw, using both previously introduced infrastructre extensions. Note that bond-speficic (and ugly) NETDEV_BONDING_INFO used by mlx4 can be removed and mlx4 can use the extensions this patchset adds. I plan to convert it and get rid of NETDEV_BONDING_INFO in a follow-up patchset. v2->v3: - one small fix in patch 1 v1->v2: - added patch 1 and 2 per Andy's request - couple of more or less cosmetic changes described in couple other patches ==================== Signed-off-by:David S.

Completion queue element for receive queue provides information if the packet was received via LAG port. Extract this info and pass it along to core. Signed-off-by:

Jiri Pirko authored
Lower layer (pci) has information if the packet is received via LAG port. If that is the case, it fills up rx_info accordingly. However upper layer does not care about lag_id/port_index for received packets so convert it to local_port before passing it up. For that conversion, lag mapping array is introduced. Upper layer is responsible for setting up the mapping according to what is set in HW. Signed-off-by:

Add just a stub for now. This allows to pass check in dev_ifsioc, SIOCADDMULTI and SIOCDELMULTI cases. Teamd is using these to add LACP slow MAC. Signed-off-by:

Be correct and symmetric to enslave and set inactive flags during release. That gives LAG offload drivers - lower state change listeners - possibility to do proper cleanup. Signed-off-by:

Let netdev notifier listeners know about link and slave state change. Signed-off-by:
-
Jiri Pirko authored
Similar to state notifications. We allow caller to indicate if the notification should happen now or later, depending on if he holds rtnl mutex or not. Introduce bond_slave_link_notify function (similar to bond_slave_state_notify) which is later on called with rtnl mutex and goes over slaves and executes delayed notification. Signed-off-by:

This is shared info structure for bonding and team. Serves to pass down info about link state and port activity to notification listeners. Signed-off-by:

Jiri Pirko authored
When lower device like bonding slave, team/bridge port, etc changes its state, it is useful for others to notice this change. Currently this is implemented specificly for bonding as NETDEV_BONDING_INFO notifier. This patch aims to replace this specific usage and make this more generic to be used for all upper-lower devices. Introduce NETDEV_CHANGELOWERSTATE netdev notifier type and netdev_lower_state_changed() helper. Signed-off-by:

Sometimes the drivers and other code would find it handy to know some internal information about upper device being changed. So allow upper-code to pass information down to notifier listeners during linking. Signed-off-by:

Ido Schimmel authored
switchdev drivers reflect the newly requested topology to hardware when CHANGEUPPER is received, after software links were already formed. However, the operation can fail and user will not be notified, as the return value of the notifier is not checked. Add this check and rollback software links if necessary. Signed-off-by:

Commit 7fd89545 ("i40e: remove BUG_ON from feature string building") added defective output when I40E_FLAG_VEB_MODE_ENABLED was set in function i40e_print_features. Fix it. Miscellanea: - Remove unnecessary string variable - Add space before not after fixed strings - Use kmalloc not kzalloc - Don't initialize i to 0, use result of first snprintf Reported-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-12-03 This series contains updates to ixgbe and ixgbevf only. Mark cleans up ixgbe_init_phy_ops_x550em, since this was designed to initialize function pointers only and moves the KR PHY reset to the ixgbe_setup_internal_phy_t_x550em which was designed to detect which mode the PHY operates in and set it up. Added the new thermal alarm type support used with newer X550EM_x devices. Fixed both ixgbe and ixgbevf to use a private work queue to avoid hangs, which would possibly occur when creating and destroying many VFS repeatedly. Updated ixgbe PTP implementation to accommodate X550EM_x devices, which handle clocking differently. Fixed specification violations in the datasheet, which was reported by Dan Streetman. Fixed ixgbe to check for and handle IPv6 extended headers so that Tx checksum offload can be done, which was reported by Tom Herbert. Fixed ixgbe link issue for some systems with X540 or X550 by only inhibiting the turning PHY power off when manageability is present. Alex Duyck refactors the MAC address configuration code, which in turns fixes an issue where once 63 entries had been used, you could no longer add additional filters. Updated ixgbe to use __dev_uc_sync which also resolved an issue in which you could not remove an FDB address without having to reset the port. Updated the ixgbe driver to make use of all the free RAR entries for FDB use if needed. v2: updated patch 13 to "Alex Duyck Approved" version, in the original submission, I had grabbed a previous version of the patch and did not catch it was superseded by a later version ==================== Signed-off-by: -

Check for and handle IPv6 extended headers so that Tx checksum offload can be done. Also use skb_checksum_help for unexpected cases. Thanks to Tom Herbert for noticing these problems. Thanks to Alexander Duyck for seeing how to coalesce the error handling into one location. Reported-by:

Instead of inhibiting PHY power control when manageability is present, only inhibit turning PHY power off when manageability is present. Consequently, PHY power will always be turned on when requested. Without this patch, some systems with X540 or X550 devices in some conditions will never get link. Signed-off-by:

Save VF device pointers and take references to speed accesses used to monitor the device behavior to avoid slot resets. The saved information avoids lock contention during the search used to access each of the VFs. Signed-off-by:

The ixgbe driver was violating the specification in the datasheet by not waiting 1ms before checking for the reset bit clearing. This is called out for devices supported by ixgbe, so implement the required delay. Reported-by:

The X550EM_x devices handle clocking differently, so update the PTP implementation to accommodate them. This involves significant changes to ixgbe's PTP code to accommodate the new range of behaviors including things like non-power-of-2 clock wrapping. Signed-off-by:

This change makes it so that we allow the PF to make use of all free RAR entries for FDB use if needed. Previously the code limited us to 16 unicast entries, however this was shared between MACVLAN which wasn't limited and the FDB code which was. So instead of treating the FDB code as a second class citizen I have updated it so that it has access to just as many entries as the MACVLAN filters. Signed-off-by:

This change replaces the ixgbe_write_uc_addr_list call in ixgbe_set_rx_mode with a call to __dev_uc_sync instead. This works much better with the MAC addr list code that was already in place and solves an issue in which you couldn't remove an FDB address without having to reset the port. Signed-off-by:
