When EEE is enabled, negotiate this feature with the PHY and make sure
that the capability checking, local EEE advertisement, link partner EEE
advertisement and auto-negotiation resolution returned by phy_init_eee()
is positive, and enable EEE at the switch level.
While querying the current EEE settings, verify the low-power indication
and indicate its status.

The SF2 switch driver is already architected around per-port
enable/disable callbacks, so we just need a slight update to our
existing bcm_sf2_port_setup() resp. bcm_sf2_port_disable() functions to
be suitable as callbacks for port_enable/port_disable.
We need to shuffle a little the code that does the per-port VLAN
configuration/isolation since ports can now be brought up/down
separately, so we need to make sure that IMP (CPU, management) port is
always included in that specific port setup.

In order for Wake-on-LAN to work properly, we query the parent network
device Wake-on-LAN features and advertise those. Similarly, when
configuring Wake-on-LAN on a per-port network interface, we make sure
that we do not accept something the master network devices does not
support.
Finally, we need to maintain a bitmask of the ports enabled for
Wake-on-LAN to prevent the suspend() callback from disabling a port that
is used for waking up the system.

Implement the suspend/resume callbacks for the Broadcom Starfighter 2
switch driver. Suspending the switch requires masking interrupts and
shutting down ports. Resuming the switch requires a software reset since
we do not know which power-sate we might be coming from, and re-enabling
the physical ports that are used.

The integrated BCM7xxx PHY contains no useful revision information
in its MII_PHYSID2 bits 3:0, that information is instead contained in
the SWITCH_REG_PHY_REVISION register.
Read this register, store its value, and return it by implementing the
dsa_switch::get_phy_flags() callback accordingly. The register layout is
already matching what the BCM7xxx PHY driver is expecting to find.

This change makes it so that instead of passing and storing a mii_bus we
instead pass and store a host_dev. From there we can test to determine the
exact type of device, and can verify it is the correct device for our switch.
So for example it would be possible to pass a device pointer from a pci_dev
and instead of checking for a PHY ID we could check for a vendor and/or device
ID.

Now that we introduced an additional multiplexing/demultiplexing layer
with commit 3e8a72d1da ("net: dsa: reduce number of protocol hooks")
that lives within the DSA code, we no longer need to have a given switch
driver tag_protocol be an actual ethertype value, instead, we can
replace it with an enum: dsa_tag_protocol.
Do this replacement in the drivers, which allows us to get rid of the
cpu_to_be16()/htons() dance, and remove ETH_P_BRCMTAG since we do not
need it anymore.

Add support for the Broadcom Starfigther 2 switch chip using a DSA
driver. This switch driver supports the following features:
- configuration of the external switch port interface: MII, RevMII,
RGMII and RGMII_NO_ID are supported
- support for the per-port MIB counters
- support for link interrupts for special ports (e.g: MoCA)
- powering up/down of switch memories to conserve power when ports are
unused
Finally, update the compatible property for the DSA core code to match
our switch top-level compatible node.

Commit 82167cb8c6 ('net: dsa/slave: Fix
compilation warnings') fixed one possible invalid configuration
(NET_DSA enabled with no trailer formats) but added others: drivers
can select NET_DSA without its dependencies being met.
It's not very useful to make either the DSA core or the tagging
formats manually selectable without a driver to use them, so:
1. Define a hidden HAVE_NET_DSA option and move the dependencies of
NET_DSA to that. While we're at it, drop the deprecated
EXPERIMENTAL dependency.
2. Make NET_DSA and the drivers dependent on HAVE_NET_DSA.
3. Hide the tagging format options again.
4. Make drivers select both NET_DSA and the appropriate tagging format
option.

Earlier approach to fix this was discussed here:
lkml.org/lkml/2012/10/29/549
This is another approach to fix it. This is done by some changes in config
options, which make more sense than the earlier approach. As, atleast one
tagging option must always be selected for using net/dsa/ infrastructure, this
patch selects NET_DSA from tagging configs instead of having it as an selectable
config.
