- Added new CGX firmware interface API for sending link up/down commands - Do link up for cgx lmac ports by default at the time of CGX driver probe. Since cgx link up in driver probe affects the Linux boot time, linkup procedure is kept threaded using workqueues. For this, a new cgx API cgx_lmac_linkup_start has been added. Signed-off-by:

For this, cgx_id(struct cgx) definition has been changed to reflect cgx port id instead of device instance id. Now cgx_id can be directly used as channel offset for NPC configuration. Assumptions on contiguous cgx port ids has been removed from nix_calibrate_x2p as well. As a side effect, allocation of conversion tables that were based on cgx count are changed to cgx port id max value. Tables would return NULL for invalid cgx ports. Signed-off-by:

When an rmb is no longer in use by a connection, unregister its rkey at the remote peer with an LLC DELETE RKEY message. With this change, unused buffers held in the buffer pool are no longer registered at the remote peer. They are registered before the buffer is actually used and unregistered when they are no longer used by a connection. Signed-off-by:

After sending one of the initial LLC messages CONFIRM LINK or ADD LINK, there is already a wait for the LLC response. It does not make sense to wait another long time for a CLC DECLINE. Thus this patch introduces a shorter wait time for these cases. Signed-off-by:

If connection initialization fails for the LLC CONFIRM LINK or the LLC ADD LINK step, fallback to TCP should be enabled. Thus the negative return code -EAGAIN should switch to a positive timeout reason code in these cases, and the internal CLC socket should not have a set sk_err. Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2018-11-21 This series contains updates to all of the Intel LAN drivers and documentation. Shannon Nelson updates the ixgbe kernel documentation to include IPsec hardware offload. Joe Perches cleans up whitespace issues in the igb driver. Jesse update the netdev kernel documentation for NETIF_F_GSO_UDP_L4 to align with the actual code. Also aligned all the NAPI driver code for all of the Intel drivers to implement the recommendations of Eric Dumazet to check the return code of the napi_complete_done() to determine whether or not to enable interrupts or exit poll. Paul E. McKenney replaces synchronize_sched() with synchronize_rcu() for ixgbe. Sasha implements suggestions made by Joe Perches to remove obsolete code and to use the dev_err() method. ==================== Signed-off-by: -

Magnus Damm says: ==================== ravb: Duplex handling update V3 [PATCH v3 01/02] ravb: Do not announce HDX as supported [PATCH v3 02/02] ravb: Clean up duplex handling This series is V3 of duplex handling improvements for the Ethernet-AVB driver. Previous versions of this series have been posted to linux-renesas-soc as RFC so V3 is the first actual version to make it to netdev. Based on the latest data sheet for R-Car Gen3 [1] and R-Car Gen2 [2] the following information is part of the EthernetAVB-IF overview page: Transfer speed: Supports transfer at 100 and 1000 Mbps Mode: Full-duplex mode It seems that the driver implementation is not matching the information provided in the friendly data sheet, and on top of this during run-time when changing PHY configuration of the link partner the Ethernet-AVB PHY seems to want to announce unsupported modes. [1] R-Car Series, 3rd Generation Rev.1.00 (Apr 2018) [2] R-Car Series, 2nd Generation Rev.2.00 (Feb 2016) Changes since V2: - Updated patch 1/2 to make use of phy_remove_link_mode() - Added Reviewed-by from Sergei - thanks!

Perform CQ initialization in the driver when the capability is supported by the FW. When passing the CQ to HW indicate that the CQ buffer has been pre-initialized. Doing so decreases CQ creation time. Testing on P8 showed a single 2048 entry CQ creation time was reduced from ~395us to ~170us, which is 2.3x faster. Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Add VxLAN learning support This patchset adds VxLAN learning support in the mlxsw driver. The first five patches from Petr add the required switchdev APIs which allow device drivers to notify the VxLAN driver about learned / aged-out FDB entries. First in patch #1, an unnecessary argument is dropped from __vxlan_fdb_delete(). In patches #2-#4, the VxLAN FDB handling code is extended to make sending the switchdev events configurable; to mark user-added entries as such; and to make sure HW-learned FDB entries do not take over user-added ones. Finally in patch #5, the necessary switchdev notifications are added and handled by VxLAN, similarly to how this is handled in the bridge driver. Patch #6 allows changing of the VxLAN's device ageing time since it is useful for the selftest in the last patch. Patch #7 adds support for querying bridge port flags of a given netdevice, as a new entry should not be learned and notified to the bridge driver in case learning is disabled on the bridge port. Next patches gradually add learning support in mlxsw. The last patch adds a new test case for VxLAN learning. ==================== Signed-off-by: -
