- Disable Routing on demand. Unused router buffers are freed and

The following time routing is enabled the default router buffer

staging: wilc1000: Return correct error codes
This change has been made with the goal that kernel functions should
return something more descriptive than -1 on failure.
The return value on an alloc_etherdev failure should be -ENOMEM,
and not -1.
This was found using Coccinelle. A simplified version of the semantic
patch used is:
//<smpl>
@@
expression *e;
identifier l1;
@@
e = alloc_etherdev(...);
if (e == NULL) {
...
return
- -1
+ -ENOMEM
;
}
//</smpl
Furthermore, introduced `ret` variable to store and return the
corresponding error code returned by register_netdev on failure.
The two call sites store the return value in a variable which only
checks that the value is non-zero, hence no change is required at
the call sites.
