Currently, setting a bridge's self PVID to other value and deleting
the default VID 1 renders untagged ports of that VLAN unable to talk to
the CPU port:
bridge vlan add dev br0 vid 2 pvid untagged self
bridge vlan del dev br0 vid 1 self
bridge vlan add dev sw0p0 vid 2 pvid untagged
bridge vlan del dev sw0p0 vid 1
# br0 cannot send untagged frames out of sw0p0 anymore
That is because the CPU port is set to security mode and its PVID is
still 1, and untagged frames are dropped due to VLAN member violation.
Set the CPU port to fallback mode so untagged frames can pass through.

Most modern broadcom PHYs support ECD (enhanced cable diagnostics). Add
support for it in the bcm-phy-lib so they can easily be used in the PHY
driver.
There are two access methods for ECD: legacy by expansion registers and
via the new RDB registers which are exclusive. Provide functions in two
variants where the PHY driver can choose from. To keep things simple for
now, we just switch the register access to expansion registers in the
RDB variant for now. On the flipside, we have to keep a bus lock to
prevent any other non-legacy access on the PHY.
The results of the intra-pair tests are inconclusive (at least for the

Configure the PRG_ETH0_ADJ_* bits to enable or disable the RX delay
based on the various RGMII PHY modes. For now the only supported RX
delay settings are:
- disabled, use for example for phy-mode "rgmii-id"
- 0ns - this is treated identical to "disabled", used for example on
boards where the PHY provides 2ns TX delay and the PCB trace length
already adds 2ns RX delay
- 2ns - for whenever the PHY cannot add the RX delay and the traces on
the PCB don't add any RX delay
Disabling the RX delay (in case u-boot enables it, which is the case
for example on Meson8b Odroid-C1) simply means that PRG_ETH0_ADJ_ENABLE,
PRG_ETH0_ADJ_SETUP, PRG_ETH0_ADJ_DELAY and PRG_ETH0_ADJ_SKEW should be
disabled (just disabling PRG_ETH0_ADJ_ENABLE may be enough, since that
disables the whole re-timing logic - but I find it makes more sense to
clear the other bits as well since they depend on that setting).
u-boot on Odroid-C1 uses the following steps to enable a 2ns RX delay:
- enabling enabling the timing adjustment clock
- enabling the timing adjustment logic by setting PRG_ETH0_ADJ_ENABLE
- setting the PRG_ETH0_ADJ_SETUP bit
The documentation for the PRG_ETH0_ADJ_DELAY and PRG_ETH0_ADJ_SKEW
registers indicates that we can even set different RX delays. However,
I could not find out how this works exactly, so for now we only support
a 2ns RX delay using the exact same way that Odroid-C1's u-boot does.

Expand the delta commit procedure for VLANs with additional logic for

For every bridge VLAN on every user port, a sub-VLAN index is calculated
and retagging rules are installed towards a dsa_8021q rx_vid that
encodes that sub-VLAN index. This way, the tagger can identify the
original VLANs.
Extra care is taken for VLANs to still work as intended in cross-chip

a sub-VLAN encoding that works for the CPU does not make any sense for a

In VLAN-unaware mode, sja1105 uses VLAN tags with a custom TPID of
0xdadb. While in the yet-to-be introduced best_effort_vlan_filtering
mode, it needs to work with normal VLAN TPID values.
A complication arises when we must transmit a VLAN-tagged packet to the
switch when it's in VLAN-aware mode. We need to construct a packet with
2 VLAN tags, and the switch will use the outer header for routing and
pop it on egress. But sadly, here the 2 hardware generations don't
behave the same:
- E/T switches won't pop an ETH_P_8021AD tag on egress, it seems
(packets will remain double-tagged).
- P/Q/R/S switches will drop a packet with 2 ETH_P_8021Q tags (it looks
like it tries to prevent VLAN hopping).
But looks like the reverse is also true:
- E/T switches have no problem popping the outer tag from packets with
2 ETH_P_8021Q tags.
- P/Q/R/S will have no problem popping a single tag even if that is
ETH_P_8021AD.
So it is clear that if we want the hardware to work with dsa_8021q
tagging in VLAN-aware mode, we need to send different TPIDs depending on
revision. Keep that information in priv->info->qinq_tpid.
The per-port tagger structure will hold an xmit_tpid value that depends
not only upon the qinq_tpid, but also upon the VLAN awareness state
itself (in case we must transmit using 0xdadb).

Managing the VLAN table that is present in hardware will become very
difficult once we add a third operating state
(best_effort_vlan_filtering). That is because correct cleanup (not too
little, not too much) becomes virtually impossible, when VLANs can be
added from the bridge layer, from dsa_8021q for basic tagging, for
cross-chip bridging, as well as retagging rules for sub-VLANs and
cross-chip sub-VLANs. So we need to rethink VLAN interaction with the
switch in a more scalable way.
In preparation for that, use the priv->expect_dsa_8021q boolean to
classify any VLAN request received through .port_vlan_add or
.port_vlan_del towards either one of 2 internal lists: bridge VLANs and
dsa_8021q VLANs.
Then, implement a central sja1105_build_vlan_table method that creates a
VLAN configuration from scratch based on the 2 lists of VLANs kept by
the driver, and based on the VLAN awareness state. Currently, if we are
VLAN-unaware, install the dsa_8021q VLANs, otherwise the bridge VLANs.
Then, implement a delta commit procedure that identifies which VLANs
from this new configuration are actually different from the config
previously committed to hardware. We apply the delta through the dynamic
configuration interface (we don't reset the switch). The result is that
the hardware should see the exact sequence of operations as before this
patch.
This also helps remove the "br" argument passed to
dsa_8021q_crosschip_bridge_join, which it was only using to figure out
whether it should commit the configuration back to us or not, based on
the VLAN awareness state of the bridge. We can simplify that, by always
allowing those VLANs inside of our dsa_8021q_vlans list, and committing
those to hardware when necessary.

At the moment, this can never happen. The 2 modes that we operate in do
not permit that:
- SJA1105_VLAN_UNAWARE: we are guarded from bridge VLANs added by the
user by the DSA core. We will later lift this restriction by setting
ds->vlan_bridge_vtu = true, and that is where we'll need it.
- SJA1105_VLAN_FILTERING_FULL: in this mode, dsa_8021q configuration is
disabled. So the user is free to add these VLANs in the 1024-3071
range.
The reason for the patch is that we'll introduce a third VLAN awareness
state, where both dsa_8021q as well as the bridge are going to call our
.port_vlan_add and .port_vlan_del methods.
For that, we need a good way to discriminate between the 2. The easiest
(and less intrusive way for upper layers) is to recognize the fact that
dsa_8021q configurations are always driven by our driver - we _know_
when a .port_vlan_add method will be called from dsa_8021q because _we_
initiated it.
So introduce an expect_dsa_8021q boolean which is only used, at the
moment, for blacklisting VLANs in range 1024-3071 in the modes when
dsa_8021q is active.

Once we're talking to the device, tell it to reset to
be sure we've got a fresh, clean environment.

Shorten our msleep time while polling for the dev command
request to finish. Yes, checkpatch.pl complains that the
msleep might actually go longer - that won't hurt, but we'll
take the shorter time if we can get it.

When going into a firmware upgrade cycle, we set the device as
not present to keep some user commands from trying to change
the driver while we're only half there. Unfortunately, the
ndo_vf_* calls don't check netif_device_present() so we need
to add a check in the callbacks.

Lots of comment cleanup for better documentation, a few new
fields added, and a few minor mistakes fixed up.

The version 1 Tx queues can use longer SG lists than the
original version 0 queues, but we need to check to see if the
firmware supports the v1 Tx queues. This implements the queue
type query for all queue types, and uses the information to
set up for using the longer Tx SG lists.
Because the Tx SG list can be longer, we need to limit the
max ring length to be sure we stay inside the boundaries of a
DMA allocation max size, so we lower the max Tx ring size.
The driver sets its highest known version in the Q_IDENTITY
command, and the FW returns the highest version that it knows,
bounded by the driver's version. The negotiated version number
is later used in the Q_INIT commands.
