Subject: [PATCH net 0/4] net: stmmac: Fix MAC-capabilities procedure

The series got born as a result of the discussions around the recent
Yanteng' series adding the Loongson LS7A1000, LS2K1000, LS7A2000, LS2K2000
MACs support:

In particular the Yanteng' patchset needed to implement the Loongson
MAC-specific constraints applied to the link speed and link duplex mode.
As a result of the discussion with Russel the next preliminary patch was
born:
Link: https://lore.kernel.org/netdev/df31e8bcf74b3b4ddb7ddf5a1c371390f16a2ad5.1712917541.git.siyanteng@loongson.cn

The patch above was a temporal solution utilized by Yanteng for further
developments and to move on with the on-going review. This patchset is a
refactored version of that single patch with formatting required for the
fixes patches.

In particular the series starts with fixing the half-duplex-less
constraint currently applied for all IP-cores. In fact it's specific for
the DW QoS Eth only (DW GMAC v4.x/v5.x).

The next patch fixes the MAC-capabilities setting up during the active
Tx/Rx queues re-initialization procedure. Particularly the procedure
missed the max-speed limit thus possibly activating speeds prohibited on
the respective platforms.

Third patch fixes the incorrect MAC-capabilities initialization for DW
MAC100, DW XGMAC and DW XLGMAC devices by moving the correct
initialization to the IP-core specific setup() methods.

Final patch is just a cleanup moving the MAC-capabilities init/re-init to
the phylink MAC-capabilities getter.

That's it for now. Thanks for review and testing in advance.
