Subject: [PATCH v3 net-next 0/7] net: dsa: add support for RTL8365MB-VC

From: Alvin Šipraga <alsi@...g-olufsen.dk>

This series adds support for Realtek's RTL8365MB-VC, a 4+1 port
10/100/1000M Ethernet switch. The driver - rtl8365mb - was developed by
Michael Ramussen and myself.

This version of the driver is relatively slim, implementing only the
standalone port functionality and no offload capabilities. It is based
on a previous RFC series [1] from August, and the main difference is the
removal of some spurious VLAN operations. Otherwise I have simply
addressed most of the feedback. Please see the respective patches for
more detail.

In parallel I am working on offloading the bridge layer capabilities,
but I would like to get the basic stuff upstreamed as soon as possible.

v2 -> v2:
  - move IRQ setup earlier in probe per Florian's suggestion
  - fix compilation error on some archs due to FIELD_PREP use in v1
  - follow Jakub's suggestion and use the standard ethtool stats API;
    NOTE: new patch in the series for relevant DSA plumbing
  - following the stats change, it became apparent that the rtl8366
    helper library is no longer that helpful; scrap it and implement
    the ethtool ops specifically for this chip

v1 -> v2:
  - drop DSA port type checks during MAC configuration
  - use OF properties to configure RGMII TX/RX delay
  - don't set default fwd_offload_mark if packet is trapped to CPU
  - remove port mapping macros
  - update device tree bindings documentation with an example
  - cosmetic changes to the tagging driver using FIELD_* macros
