* @brief Make a pipe persist through a run time reset

|

* Normally when a HCD_PORT_CMD_RESET is called, all pipes should already have been freed. However There may be cases
|
||||
* (such as during enumeration) when a pipe must persist through a reset. This function will mark a pipe as
|
||||
* persistent allowing it to survive a reset. When HCD_PORT_CMD_RESET is called, the pipe can continue to be used after
|
||||
* the reset.

* @param pipe_hdl Pipe handle
|
||||
* @retval ESP_OK: Pipe successfully marked as persistent
|
||||
* @retval ESP_ERR_INVALID_STATE: Pipe is not in a condition to be made persistent
