Currently testing #81405 with this PR. It doesn't work... Though:
I'm waiting on a new build+test with that set. |

Damned, missed that dependency. Thanks for running the tests! |

CONFIG_IP_MULTIPLE_TABLES is part of the default x86 kernel config but absent from the Aarch64 one. Adding explicitely this flag together with its dependency IP_ADVANCED_ROUTER. Both of these config flags are needed to use the routing policy facilities.

With IP_ADVANCED_ROUTER = yes the test passes.
Nice!
I added the option to this PR. We should be able to merge as soon as Hydra finish to rebuild the whole world.

Motivation for this change
Continuation of #81405 (comment)
CONFIG_IP_MULTIPLE_TABLESis part of the default x86 kernel config butabsent from the Aarch64 one. Adding this flag on the aarch64 config to
align it with the x86.
I did not use any
optionguard here: it seem like this flag is supported since Linux 2.5.45 https://cateee.net/lkddb/web-lkddb/IP_MULTIPLE_TABLES.htmlDisclaimer: I do not have access to a aarch64 machine to try this out + I don't really know what I'm doing.
