[PATCH net-next 0/8] net: dsa: realtek: rtl8365mb: add support for RTL8367S-VB

[Mieczyslaw Nalewaj <namiltd@yahoo.com>]

This series adds support for the RTL8367S-VB (chip ID 0x6642) to the
rtl8365mb driver. The chip belongs to a new "family D" that differs from
the existing family C in its VLAN table layout, speed/RGMII configuration
and SerDes (SDS13) handling.

Patch 1 detects the chip and introduces the family D branch.
Patches 2-4 add port speed, PVID read and RGMII mode configuration.
Patches 5-6 add VLAN 4k table access and PVID set/clear.
Patches 7-8 add SDS13 PCS support and re-latching of the SerDes.

Family C's functional behaviour is unchanged. The only change in a
shared path is a mutex serializing SerDes register access, added in
patch 8.

Tested on TP-Link Archer AX55 v1 (RTL8367S-VB, CPU port over HSGMII to ipq5018)
with bridge VLAN filtering and per-port PVIDs.
