Subject[PATCH net-next] net: phy: link_topology: Don't stub-away the topology creation
Date
Some of the phy_link_topology operations are protected by IS_REACHABLE,
which can lead to scenarios where the consumer, built as modules, sees the topology
unstubbed, whereas the initialization didn't occur.

Don't stub away the creation of the topology, it has no dependency on
any other parts like phylib, so we can make it always available.

Hi Nathan, Heiner,

I'm currently at EOSS, so I'm sending this patch without having been
able to properly test it (build-tested only), but as this addresses an
issue for people using -next, I'm sending this anyway, sorry about that.

Hopefully it can address the issue for now, I haven't given-up on your
idea to introduce a config option Heiner :)

Thanks,

Maxime
