+
+Print GRE key as a regular number. It is not really an IPv4 address
+and this is also how Cisco and Juniper treats GRE keys. Do keep the
+parsing of dotted-quad format for backwards compatibility.

+Similar to tunnel side: accept dotted-quad and number formats.
+Use regular number for printing the key.
+
+Signed-off-by: Timo Teräs <timo.teras@iki.fi>
+
+---
+I decided to keep using get_addr32() and get_unsigned() since uclibc
+inet_aton() does not accept all formats.
