TWT has been disabled during stabilization and further testing of the FW code. It is now considered stable, so TWT can be enabled in the driver. Signed-off-by:

A FTM responder may do PASN authentication with unassociated stations to allow secure ranging. In this case, the driver will add an internal station and install the TK so the FW will accept protected FTM request frames from this station and will send a protected FTM response frame. In addition, the driver needs to configure the HLTK to the FW so the FW can derive the secure LTF bits. This is left for a later patch since it is not yet supported by the FW. Signed-off-by:

There is an issue in the HW DMA engine in the 9000 family of devices when more than 6 RX queues are used. The issue is that the FW may hang when IWL_MVM_RXQ_NSSN_SYNC notifications are sent. Fix this by limiting the number of RX queues to 6 in the 9000 family of devices. Signed-off-by:

This patch adds a function which is able to dump firmware fifo when firmware crashes. If firmware needs more than one time to dump all logs, it will set a bit called "more bit" in the header of the first log, and driver needs to set a register to inform firmware that it is ready for the next dump.

Rtw88 currently has a function to dump reserved page section of the firmware fifo. Reserved page is just part of the firmware fifo, there are multiple sections in the firmware fifo for different usages, such as firmware rx fifo and tx fifo. This commit adds a function to check not only the reserved page section but also other parts of the firmware fifo. In addition, we need to dump firmware fifo to dump the debug log message if firmware crashes. Signed-off-by:

This handles the situation when firmware crashes. When firmware crashes, it will send an interrupt, and driver will queue a work for recovery. In the work, driver will reset it's internal association state, which includes removing associated sta's macid, resetting vifs' states and removing keys. After resetting the driver's state, driver will call rtw_enter_ips() to force the chipset power off to reset the chip. Finally, driver calls ieee80211_restart_hw() to inform mac80211 stack to restart. Since only 8822c firmware supports this feature, the interrupt will only be triggered when 8822c chipset is loaded.

Michael Chan says: ==================== bnxt_en: Update for net-next. This patch series adds 2 main features to the bnxt_en driver: 200G link speed support and FEC support with some refactoring of the link speed logic. The firmware interface is updated to have proper support for these 2 features. The ethtool preset max channel value is also adjusted properly to account for XDP and TCs. ==================== Signed-off-by: -
Michael Chan authored
The current logic that calculates the preset maximum value for combined channel does not take into account the rings used for XDP and mqprio TCs. Each of these features will reduce the number of TX rings. Add the logic to divide the TX rings accordingly based on whether the device is currently in XDP mode and whether TCs are in use.

PORT_PHY_CONFIG is always sent with REQ_FLAGS_RESET_PHY set. This flag must be set in order for the firmware to institute the requested PHY change immediately, but it results in a link flap. This is unnecessary and results in an improved user experience if the PHY reconfiguration is avoided when the user requested speed does not constitute a change. Signed-off-by:

On some 200G dual port NICs, if one port is configured to 200G, firmware will disable the ethernet link on the other port. Firmware will send notification to the driver for the disabled port when this happens. Define a new field in the link_info structure to keep track of this state. The new phy_state field replaces the unused loop_back field. Log a message when the phy_state changes state. In the disabled state, disallow any PHY configurations on the disabled port as the firmware will fail all calls to configure the PHY in this state. Reviewed-by:

The firmware interface has added support for new link speeds using PAM4 modulation. Expand the bnxt_link_info structure to closely mirror the new firmware structures. Add logic to copy the PAM4 capabilities and settings from the firmware. Signed-off-by:
-
Edwin Peer authored
It will be necessary to update more than one field in the link_info structure when PAM4 speeds are added in a later patch. Instead of merely translating ethtool speed values to firmware speed values, change the responsiblity of this function to update all the necessary link_info fields required to force the speed change to the desired ethtool value. This also reduces code duplication somewhat at the two call sites, which otherwise both have to independently update link_info fields to turn off auto negotiation advertisements. Also use the appropriate REQ_FORCE_LINK_SPEED definitions. These happen to have the same values, but req_link_speed is utilimately passed as force_link_speed in HWRM_PORT_PHY_CFG which is not defined in terms of REQ_AUTO_LINK_SPEED. Reviewed-by:

Extract the code for determining an advertised speed is no longer supported into a separate function. This will avoid some code duplication in a later patch when supporting PAM4 speeds, since these speeds are specified in a separate field. Reviewed-by:

The main changes include FEC, ECN statistics, HWRM_PORT_PHY_QCFG response size reduction, and a new counter added to ctx_hw_stats_ext struct to support the new 58818 chip. The ctx_hw_stats_ext structure is now the superset supporting the new 58818 chips and the prior P5 chips. Add a new flag to identify the new chip and use constants for the chip specific ring statistics sizes instead of the size of the structure. Because the HWRM_PORT_PHY_QCFG response structure size has shrunk back to 96 bytes, the workaround added earlier to limit the size of this message for forwarding to the VF can be removed.

Ido Schimmel says: ==================== mlxsw: Expose transceiver overheat counter Amit says: An overheated transceiver can be the root cause of various network problems such as link flapping. Counting the number of times a transceiver's temperature was higher than its configured threshold can therefore help in debugging such issues. This patch set exposes a transceiver overheat counter via ethtool. This is achieved by configuring the Spectrum ASIC to generate events whenever a transceiver is overheated. The temperature thresholds are queried from the transceiver (if available) and set to the default otherwise. Example: ... transceiver_overheat: 2 Patch set overview: Patches #1-#3 add required device registers Patches #4-#5 add required infrastructure in mlxsw to configure and count overheat events Patches #6-#9 gradually add support for the transceiver overheat counter Patch #10 exposes the transceiver overheat counter via ethtool ==================== Signed-off-by: -
