Two cases here:

1) idt77252_rx_raw() really does not make any use of the

2) idt77252_collect_stat() only uses the register values
   in code which has been compiled out by a "NOTDEF" cpp
   test for more than 10 years.  Just kill this NOTDEF
   code entirely, but keep the register reads in case

GCC complains in these queue index operations because we
perform operations of the form:

	x = some_operation(++x);

which is undefined.  Replace with:

	x = some_operation(x + 1);

which is well defined and provides the intended operation.

[ipv6] Add support for RTA_PREFSRC

This patch allows a user to select the preferred source address
for a specific IPv6-Route. It can be set via a netlink message
setting RTA_PREFSRC to a valid IPv6 address which must be
up on the device the route will be bound to.

[ipv6] Ignore looped-back NAs while in Duplicate Address Detection

If we send an unsolicited NA shortly after bringing up an
IPv6 address, the duplicate address detection algorithm
fails and the ip stays in tentative mode forever.
This is due a missing check if the NA is looped-back to us.
