);

ephandle

A Tx endpoint handle.

priority

A value from 0 (lowest) to 3 (highest). The default is queue 0 (3/highest) queue 3 (0/lowest). Queues assigned the same priority are scheduled round-robin relative to each other. Stream queues should not be set to a priority lower than normal priority queues.

Return Values

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