lib: hashing functions should take const arguments
It doesn't make much sense for a hash function to modify its argument, so const the hash input. BGP does it in a couple places, those cast away the const. Not great but not any worse than it was. Signed-off-by: Quentin Young <qlyoung@cumulusnetworks.com>
