Add the PRUeth driver for the ICSSG subsystem found in AM65x SR1.0 devices. The main differences that set SR1.0 and SR2.0 apart are the missing TXPRU core in SR1.0, two extra DMA channels for management purposes and different firmware that needs to be configured accordingly.

The only generic interface to execute asynchronously in the BH context is tasklet; however, it's marked deprecated and has some design flaws. To replace tasklets, BH workqueue support was recently added. A BH workqueue behaves similarly to regular workqueues except that the queued work items are executed in the BH context. This patch converts drivers/net/archnet/* from tasklet to BH workqueue.

Parav Pandit says: ==================== devlink: Add port function attribute for IO EQs Currently, PCI SFs and VFs use IO event queues to deliver netdev per channel events. The number of netdev channels is a function of IO event queues. In the second scenario of an RDMA device, the completion vectors are also a function of IO event queues. Currently, an administrator on the hypervisor has no means to provision the number of IO event queues for the SF device or the VF device. Device/firmware determines some arbitrary value for these IO event queues. Due to this, the SF netdev channels are unpredictable, and consequently, the performance is too. This short series introduces a new port function attribute: max_io_eqs. The goal is to provide administrators at the hypervisor level with the ability to provision the maximum number of IO event queues for a function. This gives the control to the administrator to provision right number of IO event queues and have predictable performance. Examples of when an administrator provisions (set) maximum number of IO event queues when using switchdev mode: $ devlink port show pci/0000:06:00.0/1 pci/0000:06:00.0/1: type eth netdev enp6s0pf0vf0 flavour pcivf pfnum 0 vfnum 0 function: hw_addr 00:00:00:00:00:00 roce enable max_io_eqs 10 $ devlink port function set pci/0000:06:00.0/1 max_io_eqs 20 $ devlink port show pci/0000:06:00.0/1 pci/0000:06:00.0/1: type eth netdev enp6s0pf0vf0 flavour pcivf pfnum 0 vfnum 0 function: hw_addr 00:00:00:00:00:00 roce enable max_io_eqs 20 This sets the corresponding maximum IO event queues of the function before it is enumerated. Thus, when the VF/SF driver reads the capability from the device, it sees the value provisioned by the hypervisor. The driver is then able to configure the number of channels for the net device, as well as the number of completion vectors for the RDMA device. The device/firmware also honors the provisioned value, hence any VF/SF driver attempting to create IO EQs beyond provisioned value results in an error. With above setting now, the administrator is able to achieve the 2x performance on SFs with 20 channels. In second example when SF was provisioned for a container with 2 cpus, the administrator provisioned only 2 IO event queues, thereby saving device resources. With the above settings now in place, the administrator achieved 2x performance with the SF device with 20 channels. In the second example, when the SF was provisioned for a container with 2 CPUs, the administrator provisioned only 2 IO event queues, thereby saving device resources. changelog: v2->v3: - limited to 80 chars per line in devlink - fixed comments from Jakub in mlx5 driver to fix missing mutex unlock on error path v1->v2: - limited comment to 80 chars per line in header file - fixed set function variables for reverse christmas tree - fixed comments from Kalesh - fixed missing kfree in get call - returning error code for get cmd failure - fixed error msg copy paste error in set on cmd failure ==================== Signed-off-by: -

Many devices send event notifications for the IO queues, such as tx and rx queues, through event queues. Enable a privileged owner, such as a hypervisor PF, to set the number of IO event queues for the VF and SF during the provisioning stage. example: Get maximum IO event queues of the VF device:: $ devlink port show pci/0000:06:00.0/2 pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0 vfnum 1 function: hw_addr 00:00:00:00:00:00 ipsec_packet disabled max_io_eqs 10 Set maximum IO event queues of the VF device:: $ devlink port function set pci/0000:06:00.0/2 max_io_eqs 32 $ devlink port show pci/0000:06:00.0/2 pci/0000:06:00.0/2: type eth netdev enp6s0pf0vf1 flavour pcivf pfnum 0 vfnum 1 function: hw_addr 00:00:00:00:00:00 ipsec_packet disabled max_io_eqs 32 Reviewed-by: -

The enabling/disabling of EEE in the MAC should happen as a result of auto negotiation. So move the enable/disable into lan743x_phy_link_status_change() which gets called by phylib when there is a change in link status. lan743x_ethtool_set_eee() now just programs the hardware with the LTI timer value, and passed everything else to phylib, so it can correctly setup the PHY. lan743x_ethtool_get_eee() relies on phylib doing most of the work, the MAC driver just adds the LTI timer value.

The reason codes are handled in two ways nowadays (quoting Mat Martineau): 1. Sending in the MPTCP option on RST packets when there is no subflow context available (these use subflow_add_reset_reason() and directly call a TCP-level send_reset function) 2. The "normal" way via subflow->reset_reason. This will propagate to both the outgoing reset packet and to a local path manager process via netlink in mptcp_event_sub_closed() RFC 8684 defines the skb reset reason behaviour which is not required even though in some places: A host sends a TCP RST in order to close a subflow or reject an attempt to open a subflow (MP_JOIN). In order to let the receiving host know why a subflow is being closed or rejected, the TCP RST packet MAY include the MP_TCPRST option (Figure 15). The host MAY use this information to decide, for example, whether it tries to re-establish the subflow immediately, later, or never. Since the commit dc87efdb ("mptcp: add mptcp reset option support") introduced this feature about three years ago, we can fully use it. There remains some places where we could insert reason into skb as we can see in this patch. Many thanks to Mat and Paolo for help:) Signed-off-by:Jason Xing <kernelxing@tencent.com> Acked-by:

Add a "scope" parameter to ip_route_output() so that callers don't have to override the tos parameter with the RTO_ONLINK flag if they want a local scope. This will allow converting flowi4_tos to dscp_t in the future, thus allowing static analysers to flag invalid interactions between "tos" (the DSCP bits) and ECN. Only three users ask for local scope (bonding, arp and atm). The others continue to use RT_SCOPE_UNIVERSE. While there, add a comment to warn users about the limitations of ip_route_output().

In case of stacked devices, to help propagate the down link state from the parent/root device (to this leaf device), handle NETDEV_DOWN event like it is done now for NETDEV_UP. In the below example, ens5 is the host interface which is the parent of the ipvlan interface eth0 in the container. Host: [root@gkn-podman-x64 ~]# ip link set ens5 down [root@gkn-podman-x64 ~]# ip -d link show dev ens5 3: ens5: <BROADCAST,MULTICAST> mtu 9000 qdisc mq state DOWN ... [root@gkn-podman-x64 ~]# Container: [root@testnode-ol8 /]# ip -d link show dev eth0 2: eth0@if3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 9000 state UNKNOWN ... ipvlan mode l2 bridge ... [root@testnode-ol8 /]# eth0's state continues to show up as UP even though ens5 is now DOWN. For macvlan the handling of NETDEV_DOWN event was added in commit 80fd2d6c ("macvlan: Change status when lower device goes down").

In a future patch HAS_IOPORT=n will disable inb()/outb() and friends at compile time. We thus need to add HAS_IOPORT as dependency for those drivers requiring them. For the DEFXX driver the use of I/O ports is optional and we only need to fence specific code paths. It also turns out that with HAS_IOPORT handled explicitly HAMRADIO does not need the !S390 dependency and successfully builds the bpqether driver. Acked-by:

Matthieu Baerts says: ==================== selftests: mptcp: cleanups and 'ip mptcp' support Here are some patches from Geliang, doing different cleanups, and supporting 'ip mptcp' in more MPTCP selftests. Patch 1 checks that TC is available in selftests requiring it. Patch 2 adds 'ms' units in TC commands, to avoid confusions. Patches 3-9 are some prerequisites for patch 10: some export code from mptcp_join.sh to mptcp_lib.sh, to be re-used in pm_netlink.sh, mptcp_sockopt.sh and simult_flows.sh ; and others add helpers to pm_netlink.sh to easily support both 'ip mptcp' and 'pm_nl_ctl' tools to interact with the in-kernel MPTCP path-manager. Patch 10 adds a '-i' parameter in mptcp_sockopt.sh, pm_netlink.sh, and simult_flows.sh to use 'ip mptcp' tool instead of 'pm_nl_ctl'. Patch 11 fixes some ShellCheck warnings in pm_netlink.sh, in order to drop a ShellCheck's 'disable' instruction. ==================== Signed-off-by:

If the mac address can not be read from the device registers or the devicetree, a random address is generated, but this was already done from usbnet_probe, so it is not necessary to call eth_hw_addr_random from here again to generate another random address. Indeed, when reset was also executed from bind, generate another random mac address invalidated the check from usbnet_probe to configure if the assigned mac address for the interface was random or not, because it is comparing with the initial generated random address. Now, with only a reset from open operation, it is just a harmless simplification. Signed-off-by:
