mdio: Move allocation of interrupts into core

2016-01-07T19:31:26+00:00

Have mdio_alloc() create the array of interrupt numbers, and
initialize it to POLLING. This is what most MDIO drivers want, so
allowing code to be removed from the drivers.

phy: Centralise print about attached phy

2016-01-07T19:31:25+00:00

Many Ethernet drivers contain the same netdev_info() print statement
about the attached phy. Move it into the phy device code. Additionally
add a varargs function which can be used to append additional
information.

phy: add phydev_name() wrapper

2016-01-07T19:31:25+00:00

Add a phydev_name() function, to help with moving some structure members
from phy_device.

drivers/net: remove all references to obsolete Ethernet-HOWTO

2015-06-23T13:50:35+00:00

This howto made sense in the 1990s when users had to manually configure
ISA cards with jumpers or vendor utilities, but with the implementation
of PCI it became increasingly less and less relevant, to the point where
it has been well over a decade since I last updated it.  And there is
no value in anyone else taking over updating it either.

However the references to it continue to spread as boiler plate text
from one Kconfig file into the next.  We are not doing end users any
favours by pointing them at this old document, so lets kill it with
fire, once and for all, to hopefully stop any further spread.

No code is changed in this commit, just Kconfig help text.

PCI: Remove DEFINE_PCI_DEVICE_TABLE macro use

2014-08-12T18:15:14+00:00

We should prefer `struct pci_device_id` over `DEFINE_PCI_DEVICE_TABLE` to
meet kernel coding style guidelines.  This issue was reported by checkpatch.

A simplified version of the semantic patch that makes this change is as
follows (http://coccinelle.lip6.fr/):

// 

@@
identifier i;
declarer name DEFINE_PCI_DEVICE_TABLE;
initializer z;
@@

- DEFINE_PCI_DEVICE_TABLE(i)
+ const struct pci_device_id i[]
= z;

r6040: remove empty MDIO bus reset function

2014-03-28T05:38:02+00:00

r6040_mdiobus_reset() does nothing useful and is optional for the MDIO
bus code, so let's just remove it.

r6040: use ETH_ZLEN instead of MISR for SKB length checking

2014-01-17T00:22:54+00:00

Ever since this driver was merged the following code was included:

if (skb->len < MISR)
	skb->len = MISR;

MISR is defined to 0x3C which is also equivalent to ETH_ZLEN, but use
ETH_ZLEN directly which is exactly what we want to be checking for.

r6040: add delays in MDIO read/write polling loops

2014-01-17T00:22:54+00:00

On newer and faster machines (Vortex X86DX) using the r6040 driver, it
was noticed that the driver was returning an error during probing traced
down to being the MDIO bus probing and the inability to complete a MDIO
read operation in time. It turns out that the MDIO operations on these
faster machines usually complete after ~2140 iterations which is bigger
than 2048 (MAC_DEF_TIMEOUT) and results in spurious timeouts depending
on the system load.

Update r6040_phy_read() and r6040_phy_write() to include a 1
micro second delay in each busy-looping iteration of the loop which is a
much safer operation than incrementing MAC_DEF_TIMEOUT.

drivers/net: delete non-required instances of include

2014-01-16T19:53:26+00:00

None of these files are actually using any __init type directives
and hence don't need to include .   Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

This covers everything under drivers/net except for wireless, which
has been submitted separately.

net: r6040: remove unnecessary pci_set_drvdata()

2013-10-22T06:11:52+00:00

The driver core clears the driver data to NULL after device_release
or on probe failure. Thus, it is not needed to manually clear the
device driver data to NULL.
