2019-10-09map: use ip6-full-reassembly instead of own codeKlement Sekera4-0/+70
Remove map's implementation of reassembly and use common ip6-full-reassembly functionality. This makes it easier to maintain by removing duplicate code/functionality. Type: refactor Change-Id: I430e888b704e28c100a9ce075d1460cb529e4676 Signed-off-by: Klement Sekera <ksekera@cisco.com>
