be2net: Support UE recovery in BEx/Skyhawk adapters This patch supports recovery from UEs caused due to Transient Parity Errors (TPE), in BE2, BE3 and Skyhawk adapters. This change avoids system reboot when such errors occur. The driver recovers from these errors such that the adapter resumes full operational status as prior to the UE. Following is the list of changes in the driver to support this: o The driver registers its UE recoverable capability with ARM FW at init time. This also allows the driver to know if the feature is supported in the FW. o As the UE recovery requires precise time bound processing, the driver creates its own error recovery work queue with a single worker thread (per module, shared across functions). o Each function runs an error detection task at an interval of 1 second as required by the FW. The error detection logic already exists for BEx/SH, but it now runs in the context of a separate worker thread. o When an error is detected by the task, if it is recoverable, the PF0 driver instance initiates a soft reset, while other PF driver instances wait for the reset to complete and the chip to become ready. Once the chip is ready, all driver instances including PF0, resume to reinitialize the respective functions. o The PF0 driver checks for some recovery criteria, to determine if the recovery can be initiated. If the criteria is not met, the PF0 driver does not initiate a soft reset, it retains the existing behavior to stop further processing and requires a reboot to get the chip to operational state again. o To allow each function to share the workq, while also making progress in its recovery process, a per-function recovery state machine is used. The per-function tasks avoid blocking operations like msleep() while in this state machine (until reinit state) and instead reschedule for the required delay. o With these changes, the existing error recovery code for Lancer also runs in the context of the new worker thread.

ethtool: Support for configurable RSS hash function This patch extends the set/get_rxfh ethtool-options for getting or setting the RSS hash function. It modifies drivers implementation of set/get_rxfh accordingly. This change also delegates the responsibility of checking whether a modification to a certain RX flow hash parameter is supported to the driver implementation of set_rxfh. User-kernel API is done through the new hfunc bitmask field in the ethtool_rxfh struct. A bit set in the hfunc field is corresponding to an index in the new string-set ETH_SS_RSS_HASH_FUNCS. Got approval from most of the relevant driver maintainers that their driver is using Toeplitz, and for the few that didn't answered, also assumed it is Toeplitz.

be2net: Support UE recovery in BEx/Skyhawk adapters This patch supports recovery from UEs caused due to Transient Parity Errors (TPE), in BE2, BE3 and Skyhawk adapters. This change avoids system reboot when such errors occur. The driver recovers from these errors such that the adapter resumes full operational status as prior to the UE. Following is the list of changes in the driver to support this: o The driver registers its UE recoverable capability with ARM FW at init time. This also allows the driver to know if the feature is supported in the FW. o As the UE recovery requires precise time bound processing, the driver creates its own error recovery work queue with a single worker thread (per module, shared across functions). o Each function runs an error detection task at an interval of 1 second as required by the FW. The error detection logic already exists for BEx/SH, but it now runs in the context of a separate worker thread. o When an error is detected by the task, if it is recoverable, the PF0 driver instance initiates a soft reset, while other PF driver instances wait for the reset to complete and the chip to become ready. Once the chip is ready, all driver instances including PF0, resume to reinitialize the respective functions. o The PF0 driver checks for some recovery criteria, to determine if the recovery can be initiated. If the criteria is not met, the PF0 driver does not initiate a soft reset, it retains the existing behavior to stop further processing and requires a reboot to get the chip to operational state again. o To allow each function to share the workq, while also making progress in its recovery process, a per-function recovery state machine is used. The per-function tasks avoid blocking operations like msleep() while in this state machine (until reinit state) and instead reschedule for the required delay. o With these changes, the existing error recovery code for Lancer also runs in the context of the new worker thread.
