Subject: [PATCH net-next v10 2/6] net: stmmac: Add multi-channel support
DW GMAC v3.x multi-channels feature is implemented as multiple
sets of the same CSRs. Here is only preliminary support, it will
be useful for the driver further evolution and for the users
having multi-channel DWGMAC v3.x devices.
