Merge branch 'RTL8366-stabilization'

Linus Walleij says:

====================
RTL8366 stabilization

This stabilizes the RTL8366 driver by checking validity
of the passed VLANs and refactoring the member config
(MC) code so we do not require strict call order and
de-duplicate some code.

Changes from v1: incorporate review comments on patch
2.

Changes from v2: a oneline bug fix in patch 2.
