Subject: gre: add module alias for gre0 tunnel device
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=4da6a738ffdb99b88efbe5b4c4fe521ca453640d;p=deliverable%2Flinux.git

gre: add module alias for gre0 tunnel device

If gre is built as a module the 'ip tunnel add' command would fail because
the ip_gre module was not being autoloaded.  Adding an alias for
the gre0 device name cause dev_load() to autoload it when needed.
