There are no references if_frad.h in the version of Sangoma (out of
tree) code that we use in Vyatta.

frad-0.20:src/dlcicfg.c

It includes linux/if_frad.h and also performs the DLCI_SET_CONF
ioctl.

Enough evidence to show we need to keep this header in the
export set.  Let's just kill the bogus CONFIG_* ifdef
tests in there.

After killing CONFIG_DLCI and CONFIG_DLCI_MODULE, it is also killing the
kernel:

  CC      net/socket.o
In file included from net/socket.c:75:
include/linux/if_frad.h:170: error: ‘CONFIG_DLCI_MAX’ undeclared here (not in a function)
make[1]: *** [net/socket.o] Error 1
make: *** [net] Error 2

because these things still depends on CONFIG_DLCI:

struct frad_local
{
   struct net_device_stats stats;

   /* devices which this FRAD is slaved to */
   struct net_device     *master[CONFIG_DLCI_MAX];
   short             dlci[CONFIG_DLCI_MAX];

Are you still sure we do not need CONFIG_DLCI.
