2023-12-13i40e: Fix ST code value for Clause 45Ivan Vecera1-1/+1
ST code value for clause 45 that has been changed by commit 8196b5fd6c73 ("i40e: Refactor I40E_MDIO_CLAUSE* macros") is currently wrong. The mentioned commit refactored ..MDIO_CLAUSE??_STCODE_MASK so their value is the same for both clauses. The value is correct for clause 22 but not for clause 45. Fix the issue by adding a parameter to I40E_GLGEN_MSCA_STCODE_MASK macro that specifies required value.

Dropped packets caused by too large frames were not included in dropped RX packets statistics. Issue was caused by not reading the GL_RXERR1 register. That register stores count of packet which was have been dropped due to too large size. Fix it by reading GL_RXERR1 register for each interface.

Without this patch it is possible to trigger VF reset procedure during reinit adminq. This resulted in an incorrect reading of value from the AQP registers and generated the -53 error.

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.

2020-06-26i40e: detect and log info about pre-recovery modePiotr Kwapulinski1-0/+2
Detect and log information about pre-recovery mode when firmware transitions to a recovery mode. When a firmware transitions to a recovery mode it stores a number of unexpected EMP resets in one of its registers. The number of EMP resets ranging from 0x21 to 0x2A indicates that FW transitions to recovery mode. Use these values to emit log entry about transition process. Previously the pre-recovery mode may not have been detected and there was no log entry when NIC was in pre-recovery mode.
