Ack.
There is indeed code which is not critical to basic Ethernet functionality
that can be postponed to later.

Our HW management infrastructure is rather large and contains 2 separate
mechanisms (cmdq+mbox). While I hope we can trim the driver to a VF-only
version with no ethtool support that will fit the 10KLoC ballpark, the 4KLoC
goal is probably unrealistic for a functional driver.

Is it valid to submit a non-functional kernel module and make it functional
with follow-up submissions? For example:
Submission 1: TX+RX logic
Submission 2: Device management infrastructure
Submission 3: PCI device registration and netdev creation
