[BusyBox] Silly bug in ifconfig

[Jonas Holmberg]

Could someone please commit this fix for function in_ether in ifconfig.c:

@@ -472,9 +472,9 @@
 			if (c >= '0' && c <= '9') {
 				c -= '0';
 			} else if (c >= 'a' && c <= 'f') {
-				c -= ('a' + 10);
+				c -= ('a' - 10);
 			} else if (c >= 'A' && c <= 'F') {
-				c -= ('A' + 10);
+				c -= ('A' - 10);
 			} else if (j && (c == ':' || c == 0)) {
 				break;
 			} else {

As you can see it won't get the ethernet address right if it contains a-f or A-F.
