This is what I would suggest.  Have the recipe itself set the fallback URI as
the main URL.


SRC_URI = "git://example.com/my/repository/uri;proto=https"

PREMIRRORS_prepend = "git://example.com/my/repository/uri;proto=https
git://example.com/my/otherrepo/uri;proto=ssh \n"

(the \n is literally '\' and 'n')

The above should, when it sees the SRC_URI, try the ssh protocol first.. if that
doesn't work it will fall back to SRC_URI.
