Peter[1] reported that patch cd28d1d6e52e: ("net: phy: at803x: Disable
phy delay for RGMII mode") caused regression on am335x-evmsk board.
This board expects the Phy delay to be enabled but specified RGMII mode
which refers to delays being disabled. So fix this by disabling delay only
for RGMII mode and enable for RGMII_ID and RGMII_TXID/RXID modes.

net: dsa: VLAN devices w/ filtering

This patch series supports having VLAN devices on top of DSA/switch
ports while the switch has VLAN filtering globally turned on (as is the
case with Broadcom switches). Whether the switch does global or per-port
VLAN filtering, having VLAN entries for these VLAN devices is
beneficial.

We take care of a few possibly problematic cases:

- adding a VLAN device while there is an existing VLAN entry created by
  a VLAN aware bridge. The entire bridge's VLAN database and not just
  the specific bridge port is being checked to be safe and conserative

- adding a bridge VLAN entry when there is an existing VLAN device
  created is also not possible because that would lead to the bridge
  being able to manipulate the VLAN device's VID/attributes under its feet

- enslaving a VLAN device into a VLAN aware bridge since that duplicates
  functionality already offered by the VLAN aware bridge

the switch is globally configured to do ingress/egress VID checking.

Since we can call dsa_port_vlan_{add,del} with a bridge_dev pointer
NULL, we now need to check that in these two functions.

We specifically deal with two possibly problematic cases:

- creating a bridge VLAN entry while there is an existing VLAN device
  claiming that same VID

- creating a VLAN device while there is an existing bridge VLAN entry

Spectrum-2 will be configured with a different set of pools than
Spectrum-1, their sizes will be larger, and the individual quotas will
be different as well. It is therefore necessary to make the shared
buffer module aware of this dependence on chip type, and adjust the
individual tables.

In patch #1, introduce a structure for keeping per-chip immutable and
default values.

In patch #2, structures for keeping current values of SBPM and SBPR
(pool configuration and port-pool quota) are allocated dynamically to
support varying pool counts.

In patches #3 to #7, uses of individual shared buffer configuration
tables are migrated from global definitions to fields in struct
mlxsw_sp_sb_vals, which was introduced above.

Up until this point, the actual configuration is still the one suitable
for Spectrum-1. In patch #8 Spectrum-2 configuration is added.

In patch #9, port headroom configuration is changed to take into account
current recommended value for a 100-Gbps port, and the split factor.

In patch #10, requests for overlarge headroom are rejected. This avoids

Florian Fainelli says:

====================
net: dsa: mv88e6xxx: fix IPv6

We have had some emails in private over this issue, this is my current
patch set rebased on top of net-next which provides working IPv6 (and
probably other protocols as well) over mv88e6xxx DSA switches.

The problem comes down to mv88e6xxx defaulting to not flood unknown
unicast and multicast datagrams, as they would be by dumb switches,
and as the Linux bridge code does by default.

There is also the issue of IPv6 over a vlan that is transparent to the
bridge; the multicast querier will not reach inside the vlan, and so
the switch can not learn about multicast routing within the vlan.

These flood settings can be disabled via the Linux bridge code if it's
desired to make the switch behave more like a managed switch, eg, by
enabling the multicast querier.  However, the multicast querier
defaults to being disabled which effectively means that by default,
mv88e6xxx switches block all multicast traffic.  This is at odds with
the Linux bridge documentation, and the defaults that the Linux bridge
code adopts.

So, this patch set adds DSA support for Linux bridge flags, adds
mv88e6xxx support for the unicast and multicast flooding flags, and
lastly enables flooding of these frames by default to match the
Linux bridge defaults.

5 years agonet: dsa: enable flooding for bridge ports
Russell King [Wed, 20 Feb 2019 23:35:06 +0000 (15:35 -0800)]
net: dsa: enable flooding for bridge ports

Switches work by learning the MAC address for each attached station by
monitoring traffic from each station.  When a station sends a packet,
the switch records which port the MAC address is connected to.

With IPv4 networking, before communication commences with a neighbour,
an ARP packet is broadcasted to all stations asking for the MAC address
corresponding with the IPv4.  The desired station responds with an ARP
reply, and the ARP reply causes the switch to learn which port the
station is connected to.

With IPv6 networking, the situation is rather different.  Rather than
broadcasting ARP packets, a "neighbour solicitation" is multicasted
rather than broadcasted.  This multicast needs to reach the intended
station in order for the neighbour to be discovered.

Once a neighbour has been discovered, and entered into the sending
stations neighbour cache, communication can restart at a point later
without sending a new neighbour solicitation, even if the entry in
the neighbour cache is marked as stale.  This can be after the MAC
address has expired from the forwarding cache of the DSA switch -
when that occurs, there is a long pause in communication.

Our DSA implementation for mv88e6xxx switches disables flooding of
multicast and unicast frames for bridged ports.  As per the above
description, this is fine for IPv4 networking, since the broadcasted
ARP queries will be sent to and received by all stations on the same
network.  However, this breaks IPv6 very badly - blocking neighbour
solicitations and later causing connections to stall.

The defaults that the Linux bridge code expect from bridges are for
unknown unicast and unknown multicast frames to be flooded to all ports
on the bridge, which is at odds to the defaults adopted by our DSA
implementation for mv88e6xxx switches.

This commit enables by default flooding of both unknown unicast and
unknown multicast frames whenever a port is added to a bridge, and
disables the flooding when a port leaves the bridge.  This means that
mv88e6xxx DSA switches now behave as per the bridge(8) man page, and
IPv6 works flawlessly through such a switch.
