[PATCH V2 net-next 0/6] mlxfw: Improve error reporting

[Saeed Mahameed <saeedm@mellanox.com>]

Hi Dave,

This patchset improves mlxfw error reporting of mlxfw to netlink and
kernel log.

1) patch #1, Convert extack msg to a formattable buffer

2) patch #2, Make mlxfw/mlxsw fw flash devlink status notify generic,
   and enable it for mlx5.

3) rest of the patches are improving mlxfw flash error messages by
reporting detailed mlxfw FSM error messages to netlink and more detailed
kernel log.

v2:
- Avoid long switch case and replace it with one call to NL_SET_ERR_MSG_MOD
  to format the message directly from the mlxfw_fsm_state_err_str table.

merge conflict with net:
@ drivers/net/ethernet/mellanox/mlxfw/mlxfw_fsm.c

++<<<<<<< (net-next) (keep)
+
+       if (fsm_state_err != MLXFW_FSM_STATE_ERR_OK)
+               return mlxfw_fsm_state_err(mlxfw_dev, extack, fsm_state_err);
+
++=======  
+ 
+       if (fsm_state_err != MLXFW_FSM_STATE_ERR_OK) {
+               fsm_state_err = min_t(enum mlxfw_fsm_state_err,
+                                     fsm_state_err, MLXFW_FSM_STATE_ERR_MAX);
+               pr_err("Firmware flash failed: %s\n",
+                      mlxfw_fsm_state_err_str[fsm_state_err]);
+               NL_SET_ERR_MSG_MOD(extack, "Firmware flash failed");
+               return -EINVAL;
++>>>>>>> (net) (delete) 

To resolve just use the 1st hunk, from net-next.

Thanks,
Saeed.
