    MPEHANDLE   ephandle,
    uint32_t    ns_offset
);

Parameters

ephandle

A handle for a TX endpoint.

ns_delta

Nanoseconds offset from the launch time to begin packet pre-fetch. Valid values are 0 to (65535 * 32) in 32 nanosecond increments.

Return Values

A HPESTATUS value indicating the success or failure of the operation.

Status

E_OK

The operation completed successfully.

E_EXIST

The handle given is not a valid transmit endpoint handle.

E_LIMIT
