This stat contains the number of total bits that the PHY has received; it's useful for BER calculations. Add it to the ethtool stats output. However, since this is one of the new "extra port stats", it's reported in a different manner than the existing port stats and only conditionally added to the ethtool stats output list: both the DEV_CAP_EXTRA_STATS capability must be supported by the firmware, and the firmware must set the value of the statistic to something other than IONIC_STAT_INVALID. To help support this scheme, the extra port stats region is initialized to 0xff's/IONIC_STAT_INVALID by the driver, to ensure the statistics that the driver knows about but the firmware does not are still invalid to the driver.
