i40e: allow toggling loopback mode via ndo_set_features callback

2022-12-12T23:24:47Z

Add support for NETIF_F_LOOPBACK. This feature can be set via: $ ethtool -K eth0 loopback This sets the MAC Tx->Rx loopback. This feature is used for the xsk selftests, and might have other uses too.

i40e: Fix PHY type identifiers for 2.5G and 5G adapters

2021-05-07T16:35:49Z

Unlike other supported adapters, 2.5G and 5G use different PHY type identifiers for reading/writing PHY settings and for reading link status. This commit introduces separate PHY identifiers for these two operation types.

i40e: Add hardware configuration for software based DCB

2021-02-10T22:28:39Z

Add registers and definitions required for applying DCB related hardware configuration. Add functions responsible for calculating and setting proper hardware configuration values for software based DCB functionality. Add function responsible for invoking Admin Queue command, which results in applying new DCB configuration to the hardware. Update copyright dates as appropriate. Software based DCB is a brand-new feature in i40e driver. Before, DCB was implemented by Firmware LLDP agent only. The agent was responsible for handling incoming DCB-related LLDP frames and applying received DCB configuration to hardware. New communication channel between software and hardware is required for software driver. It must be able to calculate and configure all the registers related for DCB feature.

i40e: Allow changing FEC settings on X722 if supported by FW

2020-10-14T02:44:01Z

Starting with API version 1.10 firmware for X722 devices has ability to change FEC settings in PHY. Code added in this patch allows changing FEC settings if the capability flag indicates the device supports this feature.

i40e: Set RX_ONLY mode for unicast promiscuous on VLAN

2020-08-14T22:05:05Z

Trusted VF with unicast promiscuous mode set, could listen to TX traffic of other VFs. Set unicast promiscuous mode to RX traffic, if VSI has port VLAN configured. Rename misleading I40E_AQC_SET_VSI_PROMISC_TX bit to I40E_AQC_SET_VSI_PROMISC_RX_ONLY. Aligned unicast promiscuous with VLAN to the one without VLAN.

i40e: Add support for a new feature Total Port Shutdown

2020-07-01T21:17:16Z

After OS requests to down a link on a physical network port, the traffic is no longer being processed but the physical link with a link partner is still established. Currently there is a feature (Link down on close) which allows to physically bring the link down (after OS request). With this patch new feature with similar capability is introduced: TOTAL_PORT_SHUTDOWN Allows to physically disable the link on the NIC's port. If enabled, (after link down request from the OS) no link, traffic or led activity is possible on that port. If I40E_FLAG_TOTAL_PORT_SHUTDOWN is enabled, the I40E_FLAG_LINK_DOWN_ON_CLOSE_ENABLED must be explicitly forced to true and cannot be disabled at that time. The functionalities are exclusive in terms of configuration, but they also have similar behavior (allowing to disable physical link of the port), with following differences: - LINK_DOWN_ON_CLOSE_ENABLED is configurable at host OS run-time and is supported by whole family of 7xx Intel Ethernet Controllers - TOTAL_PORT_SHUTDOWN may be enabled only before OS loads (in BIOS) only if motherboard's BIOS and NIC's FW has support of it - when LINK_DOWN_ON_CLOSE_ENABLED is used, the link is being brought down by sending phy_type=0 to NIC's FW - when TOTAL_PORT_SHUTDOWN is used, phy_type is not altered, instead the link is being brought down by clearing bit (I40E_AQ_PHY_ENABLE_LINK) in abilities field of i40e_aq_set_phy_config structure Introduced changes: - new private flag I40E_FLAG_TOTAL_PORT_SHUTDOWN for handling the feature - probe of NVM if the feature was enabled at driver's port initialization - special handling on link-down procedure to let FW physically shutdown the port if the feature was enabled Signed-off-by: Arkadiusz Kubalewski Signed-off-by: Aleksandr Loktionov Tested-by: Andrew Bowers Signed-off-by: Tony Nguyen

igb/igc: use ktime accessors for skb->tstamp

2019-11-09T00:10:51Z

When implementing launch time support in the igb and igc drivers, the skb->tstamp value is assumed to be a s64, but it's declared as a ktime_t value. Although ktime_t is typedef'd to s64 it wasn't always, and the kernel provides accessors for ktime_t values. Use the ktime_to_timespec64 and ktime_set accessors instead of directly assuming that the variable is always an s64. This improves portability if the code is ever moved to another kernel version, or if the definition of ktime_t ever changes again in the future.
