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.

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: NMichael Chan <michael.chan@broadcom.com> Signed-off-by: NDavid S.

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.

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. Add new function bnxt_fw_init_one() to re-probe the firmware and re-setup VF resources on the PF if necessary. If the re-probe fails, set a flag to prevent bnxt_open() from proceeding again.

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.

In preparation for the new firmware reset feature, some of the logic in bnxt_init_one() and related functions will be called again after firmware has reset. Reset some of the flags and capabilities so that everything that can change can be re-initialized. Refactor some functions to probe firmware versions and capabilities. Check some buffers before allocating as they may have been allocated previously. Signed-off-by: NMichael Chan <michael.chan@broadcom.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

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. This is in preparation for error recovery when firmware may be in error or reset state or Bus Master is disabled. Signed-off-by: NMichael Chan <michael.chan@broadcom.com> Signed-off-by: NDavid S.

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.

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. Convert bnxt_hwrm_do_send_msg() to return standard error code so we can do away with all the special error code handling by the many callers.

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.
