Hi Volodymyr
Please do resend it. Probably netdev will reopen sometime after the

Don't forget to include the reviewed-by i gave.

Looking at
http://www.ieee802.org/1/pages/802.1AS-rev.html
this standard hasn't even been published, and the drafts are locked
away for committee's eyes only.
So how on earth do you expect us to support it?

In genphy_config_eee_advert, the return value of phy_read_mmd_indirect is
checked to know if the register could be accessed but the result is
assigned to a 'u32'.
Changing to 'int' to correctly get errors from phy_read_mmd_indirect.

The patches regarding eee-broken-modes was merged before all people
involved could find an agreement on the best way to move forward.
While we agreed on having a DT property to mark particular modes as broken,
the value used for eee-broken-modes mapped the phy register in very direct
way. Because of this, the concern is that it could be used to implement
configuration policies instead of describing a broken HW.
In the end, having a boolean property for each mode seems to be preferred
over one bit field value mapping the register (too) directly.

The purpose of this series is to fix the integration of the ethernet phy
property "eee-broken-modes" [0]
The v3 of this series has been merged, missing a fix (error reported by
kbuild robot) available in the v4 [1]
More importantly, Florian opposed adding a DT property mapping a device
register this directly [2]. The concern was that the property could be
abused to implement platform configuration policy. After discussing it,
I think we agreed that such information about the HW (defect) should appear
in the platform DT. However, the preferred way is to add a boolean property
for each EEE broken mode.

Even if it i 100% compatible with the 6532, you should still add an
ops structure for it. All chips have their own, even when the are
exactly the same as other in the family.

Ah, err..
These should be in numerical order of the macro.
PORT_SWITCH_ID_PROD_NUM_6320 is however in the wrong place. Please
put the 6341 after the 6321.

Since the reg is 0x11, this should be called switch0phy0@11. Please
follow the same scheme for the other phys.

Hi Romain
What branch is this against? net-next?
Please see:
https://www.spinics.net/lists/netdev/msg409156.html
It would be nicer to use Volodymyr, since it has been reviewed.
Volodymyr, what happened to your version 2? Did David accept it?

There is something funky here.
When rx_handler() is called, we must have pulled Ethernet header
already.
Is this because RX_HANDLER_ANOTHER is returned in some cases, while it
should not ?
It looks like you added a pskb_may_pull() at a wrong place. Sure it
might fix the crash, but it looks weird here.

Two cases that I've been aware of are nested virt or simply a guest acting

Some Marvell ethernet switches have internal ethernet transceivers with
hardcoded phy addresses. These addresses can be grearer than the number
of ports or its value might be different than the associated port number.
This is for example the case for MV88E6341 that has 6 ports and internal
Port 1 to Port4 PHYs mapped at SMI addresses from 0x11 to 0x14.
This commits fixes the issue by removing the condition in MDIO callbacks.

The Marvell 88E6341 device is single-chip, 6-port ethernet switch with
four integrated 10/100/1000Mbps ethernet transceivers and one high speed
SerDes interfaces. It is compatible with switches of family 88E6352.
This commit adds basic support for this switch by describing its
capabilities to the driver.

I've not looked closely, but is that (in some sense) duplicating
the key length?
So you could set a = key[2] and b = key[3] and still have an
working hash - albeit not exactly the one specified.
I'll add another comment here...
Is it worth using the 32bit hash for IP addresses on 64bit systems that
can't do misaligned accessed?
