Tom Herbert 707a2ca487 ila: Perform only one translation in forwarding path ... When setting up ILA in a router we noticed that the the encapsulation is invoked twice: once in the route input path and again upon route output. 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. The router translates SIR addresses between the two destinations in other two netns. Verified ping and netperf are functional. Signed-off-by: Tom Herbert <tom@herbertland.com> Signed-off-by: David S.
