2020-09-24mptcp: send out ADD_ADDR with echo flagGeliang Tang
When the ADD_ADDR suboption has been received, we need to send out the same ADD_ADDR suboption with echo-flag=1, and no HMAC.

2020-09-24mptcp: add the incoming RM_ADDR supportGeliang Tang
This patch added the RM_ADDR option parsing logic: We parsed the incoming options to find if the rm_addr option is received, and called mptcp_pm_rm_addr_received to schedule PM work to a new status, named MPTCP_PM_RM_ADDR_RECEIVED. PM work got this status, and called mptcp_pm_nl_rm_addr_received to handle it. In mptcp_pm_nl_rm_addr_received, we closed the subflow matching the rm_id, and updated PM counter.

This patch added a new signal named rm_addr_signal in PM. On outgoing path, we called mptcp_pm_should_rm_signal to check if rm_addr_signal has been set.

git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2020-09-22 This series includes mlx5 updates 1) Add support for Connection Tracking offload in NIC mode. Supporting CT offload in NIC mode on Mellanox cards is useful for scenarios where the dual port NIC serves as a gateway between 2 networks and forwards traffic between these networks. Since the traffic is not terminated on the host in this case, no use of SRIOV VFs and/or switchdev mode is required. Today Mellanox NIC cards already support offloading of packet forwarding between physical ports without going to the host so combining it with CT offloading allows users to create a gateway with forwarding and CT (Including NAT) offloading capabilities in non-switchdev mode. To support connection tracking in non-Switchdev mode (Single NIC mode), we need to make use of the current Connection tracking infrastructure implemented on top of E-Switch and the mlx5 generic flow table chains APIs, to make it work on non-Eswitch steering domain e.g. NIC RX domain, the following was performed: 1.1) Refactor current flow steering chains infrastructure and updates TC nic mode implementation to use flow table chains. 1.2) Refactor current Connection Tracking (CT) infrastructure to not assume E-switch backend, and make the CT layer agnostic to underlying steering mode (E-Switch/NIC) 1.3) Plumbing to support CT offload in NIC mode. 2) Trivial code cleanups. ==================== Signed-off-by: David S.

Ioana Ciornei says: ==================== dpaa2-mac: add PCS support through the Lynx module This patch set aims to add PCS support in the dpaa2-eth driver by leveraging the Lynx PCS module. The first two patches are some missing pieces: the first one adding support for 10GBASER in Lynx PCS while the second one adds a new function - of_mdio_find_device - which is helpful in retrieving the PCS represented as a mdio_device. The final patch adds the glue logic between phylink and the Lynx PCS module: it retrieves the PCS represented as an mdio_device and registers it to Lynx and phylink. From that point on, any PCS callbacks are treated by Lynx, without dpaa2-eth interaction. Changes in v2: - move put_device() after destroy - 3/3 ==================== Signed-off-by: David S.

2020-09-24dpaa2-mac: add PCS support through the Lynx moduleIoana Ciornei
Include PCS support in the dpaa2-eth driver by integrating it with the new Lynx PCS module. There is not much to talk about in terms of changes needed in the dpaa2-eth driver since the only steps necessary are to find the MDIO device representing the PCS, register it to the Lynx PCS module and then let phylink know if its existence also. After this, the PCS callbacks will be treated directly by Lynx, without interraction from dpaa2-eth's part.

2020-09-24net: mscc: ocelot: always pass skb clone to ocelot_port_add_txtstamp_skbVladimir Oltean
Currently, ocelot switchdev passes the skb directly to the function that enqueues it to the list of skb's awaiting a TX timestamp. Whereas the felix DSA driver first clones the skb, then passes the clone to this queue. This matters because in the case of felix, the common IRQ handler, which is ocelot_get_txtstamp(), currently clones the clone, and frees the original clone. This is useless and can be simplified by using skb_complete_tx_timestamp() instead of skb_tstamp_tx().
