PS1:
Several comments:
* Do we really want to have this configurable over envvar? what's the reasoning? to be able to temporarily spot failures and compare?
* It probably makes sense to change the patch to do the following, to avoid calling io_uring_submit() every loop iteration unconditionally:
* in rubmit_rx, submit_tx, etc, if we had to call io_uring_submit() then set some new global var "io_uring_submit_needed" to true.
* during the poll loop iteration, only call io_uring_submit() if the var was set to true, and set it to false again.

Change subject: vty: Make sure user doesn't configure AS in ASP role with a non-local PC as routing-key
......................................................................
vty: Make sure user doesn't configure AS in ASP role with a non-local PC as routing-key
AS in ASP mode doesn't expect to route incomign traffic to other nodes.
They are expected to announce its routing-key (local PC) to the SG so it
knows how to reach it and in turn announce (un)availability to other
SG/ASPs in the network.
