net: phy: realtek: handle RX delay setting ...

RX delay and TX delay can be configured independently on the RTL8211F.
Decode the phy mode setting and set both bits accordingly. This is based
on Linux commit 1b3047b5208a ("net: phy: realtek: add support for
configuring the RX delay on RTL8211F")

net: cpsw: add vlan handling for dual_emac mode ...

From TI am335x Reference Manual:

14.3.2.10.2 Dual Mac Mode

When operating in dual mac mode the intention is to transfer packets
between ports 0 and 1 and ports 0 and 2, but not between ports 1 and 2.

Each CPGMAC_SL appears as a single MAC with no bridging between MAC’s.
Each CPGMAC_SL has at least one unique (not the same) mac address.

Dual mac mode is configured as described below:

- Set the ale_vlan_aware bit in the ALE_Control register. This bit
configures the ALE to process in vlan aware mode.

With X can be Port 1 or Port 2:

- Configure the Port X to Port 0 VLAN.
Add a VLAN Table Entry with ports 0 and X as members (clear the flood
masks).

Add a VLAN/Unicast Address Table Entry with the PortX/0 VLAN and
a port number of 0.

- Select the dual mac mode on the port 0 FIFO by setting
tx_in_sel[1:0] = 01 in P0_Tx_In_Ctl.

net: cpsw: cpsw_process should only handle rx channels for its own port ...

The driver is currently processing the whole channel list, so it is
possible that it handles a channel of the wrong interface. We limit the
rx_chan handling for its desired port.

The cpsw_send is removing finished tx_chan transfers on each send, so this
has no directional limitation.
