2019-08-30bnxt_en: Add bnxt_fw_exception() to handle fatal firmware errors.Michael Chan2-0/+45
This call will handle fatal firmware errors by forcing a reset on the firmware. The master function driver will carry out the forced reset. The sequence will go through the same bnxt_fw_reset_task() workqueue. This fatal reset differs from the non-fatal reset at the beginning stages. From the BNXT_FW_RESET_STATE_ENABLE_DEV state onwards where the firmware is coming out of reset, it is practically identical to the non-fatal reset. The next patch will add the periodic heartbeat check and the devlink reporter to report the fatal event and to initiate the bnxt_fw_exception() call.

2019-08-30bnxt_en: Do not send firmware messages if firmware is in error state.Michael Chan2-7/+12
Add a flag to mark that the firmware has encountered fatal condition. The driver will not send any more firmware messages and will return error to the caller. Fix up some clean up functions to continue and not abort when the firmware message function returns error. This is preparation work to fully handle firmware error recovery under fatal conditions.

2019-08-30bnxt_en: Add devlink health reset reporter.Vasundhara Volam4-0/+61
Add devlink health reporter for the firmware reset event. Once we get the notification from firmware about the impending reset, the driver will report this to devlink and the call to bnxt_fw_reset() will be initiated to complete the reset sequence.

2019-08-30bnxt_en: Handle firmware reset.Michael Chan3-0/+164
Add the bnxt_fw_reset() main function to handle firmware reset. This is triggered by firmware to initiate an orderly reset, for example when a non-fatal exception condition has been detected. bnxt_fw_reset() will first wait for all VFs to shutdown and then start the bnxt_fw_reset_task() work queue to go through the sequence of reset, re-probe, and re-initialization. The next patch will add the devlink reporter to start the sequence and call bnxt_fw_reset(). Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

2019-08-30bnxt_en: Handle RESET_NOTIFY async event from firmware.Michael Chan2-0/+18
This event from firmware signals a coordinated reset initiated by the firmware. It may be triggered by some error conditions encountered in the firmware or other orderly reset conditions. We store the parameters from this event. Subsequent patches will add logic to handle reset itself using devlink reporters.

2019-08-30bnxt_en: Add BNXT_STATE_IN_FW_RESET state.Michael Chan3-0/+26
The new flag will be set in subsequent patches when firmware is going through reset. If bnxt_close() is called while the new flag is set, the FW reset sequence will have to be aborted because the NIC is prematurely closed before FW reset has completed. We also reject SRIOV configurations while FW reset is in progress. v2: No longer drop rtnl_lock() in close and wait for FW reset to complete.

During IF_UP, newer firmware has a new status flag that indicates that firmware has reset.

2019-08-30bnxt_en: Register buffers for VFs before reserving resources.Vasundhara Volam1-5/+5
When VFs need to be reconfigured dynamically after firmwware reset, the configuration sequence on the PF needs to be changed to register the VF buffers first. Otherwise, some VF firmware commands may not succeed as there may not be PF buffers ready for the re-directed firmware commands. This sequencing did not matter much before when we only supported the normal bring-up of VFs.

If the silent parameter is set, suppress all messages when there is no response from firmware. When polling for firmware to come out of reset, no response may be normal and we want to suppress the error messages. Also, don't poll for the firmware DMA response if Bus Master is disabled.

2019-08-30bnxt_en: Simplify error checking in the SR-IOV message forwarding functions.Michael Chan1-64/+8
There are 4 functions handling message forwarding for SR-IOV. They check for non-zero firmware response code and then return -1. There is no need to do this anymore. The main messaging function will now return standard error code. Since we don't need to examine the response, we can use the hwrm_send_message() variant which will take the mutex automatically.

2019-08-30bnxt_en: Convert error code in firmware message response to standard code.Michael Chan6-77/+44
The main firmware messaging function returns the firmware defined error code and many callers have to convert to standard error code for proper propagation to userspace.

2019-08-29net: spider_net: Use struct_size() helperGustavo A. R. Silva1-4/+2
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct spider_net_card { ... struct spider_net_descr darray[0]; }; Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(struct spider_net_card) + (tx_descriptors + rx_descriptors) * sizeof(struct spider_net_descr) with: struct_size(card, darray, tx_descriptors + rx_descriptors) Notice that, in this case, variable alloc_size is not necessary, hence it is removed.
