Subject: [PATCH 02/10] dahdi-base, netdev: send frame via protocol handlers,
 fix HDLC encapsulation

The HDLC encapsulation module can add its own headers and trailers to
the packet. For correct operation in this case, it is necessary to send
a packet from DAHDI to the appropriate HDLC handler. The HDLC handler,
in turn, should call the device driver procedure to transfer the packet.

Thus, for correct processing of outgoing packets, we should use function
hdlc_start_xmit from Linux HDLC stack as a ndo_start_xmit procedure.

(Note that if the protocol handler does not provide a xmit procedure,
then function hdlc_start_xmit will call the hardware driver directly.)

In the case of DAHDI, the packet transfer procedure (device driver xmit
procedure) is set in function dahdi_ioctl_chanconfig to dahdi_xmit:

dev_to_hdlc(chan->hdlcnetdev->netdev)->xmit = dahdi_xmit;
