Add the bnxt_stats_get_op() and bnxt_stats_reset_op() dev_ops to get and reset statistics. It also brings in the associated HWRM calls to handle the requests appropriately. We also have the bnxt_free_stats() function which will be used in the follow on patches to free the memory allocated by the driver for statistics. New HWRM calls: bnxt_hwrm_stat_clear: This command clears statistics of a context Signed-off-by: Ajit Khaparde <ajit.khaparde@broadcom.com> Signed-off-by: Stephen Hurd <stephen.hurd@broadcom.com> Reviewed-by: David Christensen <david.christensen@broadcom.com>
