Subject: [PATCH net-next v3 0/7] net: axienet: Fix deferred probe loop

Fix a deferred-probe loop by splitting the MAC and MDIO functionality
into separate drivers. Please refer to the last patch for an extended
look at the problem this series is attempting to solve.

This is a rather large fix for a rather rare bug, so I have sent it
for net-next. The first patch is a smaller fix, however, and could go
via net.

Changes in v3:
- Use ioread32/iowrite32 directly in MDIO
- Use MDIO bus device in prints
- Use device variable to probe
- Rework to use a separate axienet_common structure, as netdevs cannot
  be reused once registered.
- Use ida_alloc for aux id

Changes in v2:
- Fix building as a module
- Expand commit message with much more info on the problem and possible
  solutions
