In normal cases, we expect to have

• 1...n phy_links
  • with each 1..n phy_instances
• each phy_instance mapped to one TRX

However, in some cases people want to have configurations where certain TRX are by-passed. Imagine situations where a TRX has become defective in some way.
In such cases, we might end up having:

• any number of phy_links/phy_instances without a TRX mapped to them
• TRX0 mapped to any of the remaining phy_instances.

We should properly support such configurations and verify that they are functional. Verification should happen on osmo-bts-litecell15.
