Description
This function resets or collects the statistics on a network interface. If the size of the statistics table
specified by StatisticsSize is not big enough for all the statistics that are collected by the
network interface, then a partial buffer of statistics is returned in StatisticsTable,
StatisticsSize is set to the size required to collect all the available statistics, and
EFI_BUFFER_TOO_SMALL is returned.
If StatisticsSize is big enough for all the statistics, then StatisticsTable will be filled,
StatisticsSize will be set to the size of the returned StatisticsTable structure, and
EFI_SUCCESS is returned. If the driver has not been initialized, EFI_DEVICE_ERROR will be
returned.
If Reset is FALSE, and both StatisticsSize and StatisticsTable are NULL, then no
operations will be performed, and EFI_SUCCESS will be returned.
If Reset is TRUE, then all of the supported statistics counters on this network interface will be
reset to zero.
Status Codes Returned
EFI_SUCCESS The statistics were collected from the network interface.
EFI_NOT_STARTED The network interface has not been started.
EFI_BUFFER_TOO_SMALL
The
Statistics buffer was too small. The current buffer size
needed to hold the statistics is returned in
StatisticsSize.
EFI_INVALID_PARAMETER One or more of the parameters has an unsupported value.
EFI_DEVICE_ERROR The command could not be sent to the network interface.
EFI_UNSUPPORTED This function is not supported by the network interface.
