This function resets or collects the statistics on a network interface. If the\r
size of the statistics table specified by StatisticsSize is not big enough for\r
all the statistics that are collected by the network interface, then a partial\r
- buffer of statistics is returned in StatisticsTable, StatisticsSize is set to \r
- the size required to collect all the available statistics, and \r
+ buffer of statistics is returned in StatisticsTable, StatisticsSize is set to\r
+ the size required to collect all the available statistics, and\r
EFI_BUFFER_TOO_SMALL is returned.\r

- will be filled, StatisticsSize will be set to the size of the returned \r
+ If StatisticsSize is big enough for all the statistics, then StatisticsTable\r
+ will be filled, StatisticsSize will be set to the size of the returned\r
StatisticsTable structure, and EFI_SUCCESS is returned.\r
If the driver has not been initialized, EFI_DEVICE_ERROR will be returned.\r
If Reset is FALSE, and both StatisticsSize and StatisticsTable are NULL, then\r
