[En-Nut-Discussion] HDLC_SETIFNET bug.

[Francois Rademeyer]

Hi,

There is a bug in "ahdlcavr.c" at line 410:

if (dev->dev_icb == 0)
 break;

only exits the first while loop, but should in fact exit the for(;;) loop
aswell.

This bug both prohibits the closure of a PPP connection, aswell as the
working of the command _ioctl(dev, HDLC_SETIFNET, NULL).

Cheers,
Francois
