[net-next,v3,0/2] Refactoring designware VLAN code.

Message

Ng, Boon Khai April 8, 2025, 8:13 a.m. UTC

Refactoring designware VLAN code and introducing support for
hardware-accelerated VLAN stripping for dwxgmac2 IP,
the current patch set consists of two key changes:

1) Refactoring VLAN Functions:
The first change involves moving common VLAN-related functions
of the DesignWare Ethernet MAC into a dedicated file, stmmac_vlan.c.
This refactoring aims to improve code organization and maintainability
by centralizing VLAN handling logic.

2) Enabling VLAN for 10G Ethernet MAC IP:
The second change enables VLAN support specifically
for the 10G Ethernet MAC IP. This enhancement leverages
the hardware capabilities of the to perform VLAN stripping,

Changes from previous submmited patches.
v2:
The hardware VLAN enablement switch was detached from the
device tree source (DTS). Instead, the hardware VLAN enablement
is now dynamically determined in stmmac_main.c based on the
currently running IP.

v1:
The initial submission introduced hardware VLAN support for the
10G Ethernet MAC IP.
