The new CPSW ALE version, available on TI K3 AM654/J721E SoCs family,
allows to switch any external port to MAC only mode. When MAC only mode
enabled this port be treated like a MAC port for the host. All traffic
received is only sent to the host. The host must direct traffic to this
port as the lookup engine will not send traffic to the ports with the
p0_maconly bit set and the p0_no_learn also set. If p0_maconly bit is set
and the p0_no_learn is not set, the host can send non-directed packets that
can be sent to the destination of a MacOnly port. It is also possible that
The host can broadcast to all ports including MacOnly ports in this mode.
This patch add ALE supprt for MAC only mode.

A following patch introduces switchdev functionality, so modify
ALE engine VLANs/MDBs API:
- cpsw_ale_del_mcast(): update so it will remove only selected ports from
mcast port_mask or delete whole mcast record if !port_mask
- cpsw_ale_del_vlan(): update so it will remove only selected ports from
all VLAN record's masks or delete whole VLAN record if !port_mask
- add cpsw_ale_vlan_add_modify() to add or modify existing VLAN record's
masks
- add cpsw_ale_set_unreg_mcast() for enabling unreg mcast on port VLANs

Now untagged vlan traffic is not support on Host P0 port. This patch adds
in ALE context bitmap of VLANs for which Host P0 port bit set in Force
Untagged Packet Egress bitmask in VLANs ALE entries, and adds corresponding
check in VLAN incapsulation header parsing function cpsw_rx_vlan_encap().

Now CPSW ALE will set/clean Host port bit in Unregistered Multicast Flood
Mask (UNREG_MCAST_FLOOD_MASK) for every VLAN without checking if this port
belongs to VLAN or not when ALLMULTI mode flag is set for nedev. This is
working in non dual_mac mode, but in dual_mac - it causes
enabling/disabling ALLMULTI flag for both ports.
Hence fix it by adding additional parameter to cpsw_ale_set_allmulti() to
specify ALE port number for which ALLMULTI has to be enabled and check if
port belongs to VLAN before modifying UNREG_MCAST_FLOOD_MASK.

For NetCP NU Switch ALE, some of the mask bits are different than
defaults used in the driver. Add a new macro DEFINE_ALE_FIELD1 that use
a configurable mask bits and use it in the driver. These bits are set to
correct values by using the new variables added to cpsw_ale structure
and re-used in the macros. The parameter nu_switch_ale is configured by
the caller driver to indicate the ALE is for that switch and is used in
the ALE driver to do customization as needed.

In NU Ethernet switch used on some of the Keystone SoCs, there is
separate UNKNOWNVLAN register for membership, unreg mcast flood, reg
mcast flood and force untag egress bits in ALE. So control for these
fields require different address offset, shift and size of field.
As this ALE has the same version number as ALE in CPSW found on other
SoCs, customization based on version number is not possible. So
use a configuration parameter, nu_switch_ale, to identify the ALE
ALE found in NU Switch. Different treatment is needed for NU Switch
ALE due to difference in the ale table bits, separate unknown vlan
registers etc. The register information available in ale_controls,
needs to be updated to support the netcp NU switch h/w. So it is not
constant array any more since it needs to be updated based
on ALE type. The header of the file is also updated to indicate it
supports N port switch ALE, not just 3 port. The version mask is
3 bits in NU Switch ALE vs 8 bits on other ALE types.
While at it, change the debug print to info print so that ALE
version gets displayed in boot log.

Since ALE table is a common resource for both the interfaces in Dual EMAC
mode and while bringing up the second interface in cpsw_ndo_set_rx_mode()
all the multicast entries added by the first interface is flushed out and
only second interface multicast addresses are added. Fixing this by
flushing multicast addresses based on dual EMAC port vlans which will not
affect the other emac port multicast addresses.

The cpsw driver did not support the IFF_ALLMULTI flag which makes dynamic
multicast routing not work. Related to this, when enabling IFF_PROMISC
in switch mode, all registered multicast addresses are flushed, resulting
in only broadcast and unicast traffic being received.
A new cpsw_ale_set_allmulti function now scans through the ALE entry
table and adds/removes the host port from the unregistered multicast
port mask of each vlan entry depending on the state of IFF_ALLMULTI.
In promiscious mode, cpsw_ale_set_allmulti is used to force reception
of all multicast traffic in addition to the unicast and broadcast traffic.
With this change dynamic multicast and promiscious mode both work in
switch mode.
