To resolve this we add a flag set_csum_neutral for the > ila_update_ipv6_locator. If this flag is set and the checksum > neutral bit is also set we assume that checksum-neutral translation > has already been performed and take no further action. The > flag is set only in ila_output path. The flag is not set for ila_input and > ila_xlat. > > Tested: > > Used 3 netns to set to emulate a router and two hosts.
