Currently if a unicast MAC is set via ndo_set_vf_mac, the PF driver will set the VF's dflt_lan_addr.addr once some basic checks have passed. The VF is then reset. During reset the PF driver will attempt to program the VF's MAC from the dflt_lan_addr.addr field. This fails when the MAC already exists on the PF's switch. This is causing the VF to be completely disabled until removing/enabling any VFs via sysfs. Fix this by checking if the unicast MAC exists before triggering a VF reset directly in ndo_set_vf_mac. Also, add a check if the unicast MAC is set to the same value as before and return 0 if that is the case. Signed-off-by:

Currently if the iavf is loaded and a VF link transitions from up to down to up again a Tx timeout will be triggered. This happens because Tx/Rx queue interrupts are only enabled when receiving the VIRTCHNL_OP_CONFIG_MAP_IRQ message, which happens on reset or initial iavf driver load, but not when bringing link up. This is problematic because they are disabled on the VIRTCHNL_OP_DISABLE_QUEUES message, which is part of bringing a VF's link down. However, they are not enabled on the VIRTCHNL_OP_ENABLE_QUEUES message, which is part of bringing a VF's link up. Fix this by re-enabling the VF's Rx and Tx queue interrupts when they were previously configured. This is done by first checking to make sure the previous value in QINT_[R|T]QCTL.MSIX_INDX is not 0, which is used to represent the OICR in the VF's interrupt space. If the MSIX_INDX is non-zero then enable the interrupt by setting the QINT_[R|T]CTL.CAUSE_ENA bit to 1. Signed-off-by:

Enable accelerated Receive Flow Steering (aRFS). It is used to steer Rx flows to a specific queue. This functionality is triggered by the network stack through ndo_rx_flow_steer and requires Flow Director (ntuple on) to function. The fltr_info is used to add/remove/update flow rules in the HW, the fltr_state is used to determine what to do with the filter with respect to HW and/or SW, and the flow_id is used in co-ordination with the network stack. The work for aRFS is split into two paths: the ndo_rx_flow_steer operation and the ice_service_task. The former is where the kernel hands us an Rx SKB among other items to setup aRFS and the latter is where the driver adds/updates/removes filter rules from HW and updates filter state. In the Rx path the following things can happen: 1. New aRFS entries are added to the hash table and the state is set to ICE_ARFS_INACTIVE so the filter can be updated in HW by the ice_service_task path. 2. aRFS entries have their Rx Queue updated if we receive a pre-existing flow_id and the filter state is ICE_ARFS_ACTIVE. The state is set to ICE_ARFS_INACTIVE so the filter can be updated in HW by the ice_service_task path. 3. aRFS entries marked as ICE_ARFS_TODEL are deleted In the ice_service_task path the following things can happen: 1. New aRFS entries marked as ICE_ARFS_INACTIVE are added or updated in HW. and their state is updated to ICE_ARFS_ACTIVE. 2. aRFS entries are deleted from HW and their state is updated to ICE_ARFS_TODEL.

Flex-bytes allows for packet matching based on an offset and value. This is supported via the ethtool user-def option. It is specified by providing an offset followed by a 2 byte match value. Offset is measured from the start of the MAC address. The following restrictions apply to flex-bytes. The specified offset must be an even number and be smaller than 0x1fe. Example usage: ethtool -N eth0 flow-type tcp4 src-ip 192.168.0.55 dst-ip 172.16.0.55 \ src-port 12 dst-port 13 user-def 0x10ffff action 32 Signed-off-by:

Change min() macros to min_t() which has compare type specified and it helps avoid precision loss. In some cases there was precision loss during calls or assignments. Some fields in structs were unnecessarily large and gave multiple warnings. There were also some minor type differences which are now fixed as well as some cases where a simple cast was needed. Callers were were passing data that is a u16 to ice_sched_cfg_node_bw_alloc() but the function was truncating that to a u8. Fix that by changing the function to take a u16. Signed-off-by:

As soon as the driver registers the PF netdev, userspace utilities like NetworkManager try to bring up the associated interface. When this happens, the driver may not have finished initializing fully, resulting in a bunch of errors in the interface up flow. The driver already has a mechanism to indicate if it's not up yet; by setting the __ICE_DOWN bit in pf->state, but this bit gets cleared too early in the current flow. So clear this bit only when the driver is fully up. Also check for the same bit in the ice_open flow, and return -EBUSY if the bit is set. Also in ice_open, replace references of vsi->back with a local variable. Signed-off-by:

Currently, the ice driver is setting a PHY configuration, which causes a link drop, and then additionally it calls for a nway_reset, which restarts auto-negotiation on the link, which also causes a link drop. These two link events in such close timing is causing the FW to not be able to generate a link interrupt for the driver to respond to. Remove the unnecessary auto-negotiation restart from the set pauseparams flow. Also remove error path that would have performed an ice_down/ice_up as that is also unnecessary. Signed-off-by:

When there's a Tx timeout for a queue which belongs to a PFC enabled TC, then it's not because the queue is hung but because PFC is in action. In PFC, peer sends a pause frame for a specified period of time when its buffer threshold is exceeded (due to congestion). Netdev on the other hand checks if ACK is received within a specified time for a TX packet, if not, it'll invoke the tx_timeout routine. Signed-off-by:

Implement promiscuous support for VF VSIs. Behaviour of promiscuous support is based on VF trust as well as the, introduced, vf-true-promisc flag. A trusted VF with vf-true-promisc disabled will be the default VSI, which means that all traffic without a matching destination MAC address in the device's internal switch will be forwarded to this VF VSI. A trusted VF with vf-true-promisc enabled will go into "true promiscuous mode". This amounts to the VF receiving all ingress and egress traffic that hits the device's internal switch. An untrusted VF will only receive traffic destined for that VF. The vf-true-promisc-support flag cannot be toggled while any VF is in promiscuous mode. This flag should be set prior to loading the iavf driver or spawning VF(s). Signed-off-by:
