This is something I thought about for a while. Since DSA offers an
abstraction of different net stack entry points to its drivers, like
netlink (bridge, etc.) or ioctl (ethtool), it would make sense to add a

There are various upper locks, which protect some calls, in some ways.

I did not include any locking in the code I contributed to lan9303.
First I felt bad locking is worse than no locking. Second I assumed that
reviewers would point out if locking
