Elsukov AuthorDate: 2021-11-02 16:59:06 +0000 Commit: Andrey V. Elsukov CommitDate: 2021-11-12 12:20:46 +0000 ip_divert: calculate delayed checksum for IPv6 adress family Before passing an IPv6 packet to application apply delayed checksum calculation. Mbuf flags will be lost when divert listener will return a packet back, so we will not be able to do delayed checksum calculation later. Also an application will get a packet with correct checksum.
