mISDN: Implement MISDN_CTRL_FILL_EMPTY for more drivers
MISDN_CTRL_FILL_EMPTY is a meachanism to send a fixed value (normally silence) as long no data from upper layers is available. It can be used when recording voice messages or with unidirectional protocols. Signed-off-by: Karsten Keil <kkeil@linux-pingi.de> Signed-off-by: David S. Miller <davem@davemloft.net>
