Implement support for sticky (static) MACs. This includes the following: - Recognize MAC is static (using NUD_NOARP flag) and inform BGP - Construct MAC mobility extended community for sticky MACs as per RFC 7432 section 15.2 - Inform to zebra that remote MAC is sticky, where appropriate - Install sticky MACs into the kernel with the right flag - Appropriate handling in route selection Signed-off-by: Daniel Walton <dwalton@cumulusnetworks.com> Reviewed-by: Vivek Venkatraman <vivek@cumulusnetworks.com> Reviewed-by: Donald Sharp <sharpd@cumulusnetworks.com>
