net: turn name len check into an assert

2011-09-21T21:04:34+00:00

The new sanity check introduces a printf warning for some systems:
	eth.c:233: warning: format '%zu' expects type 'size_t', but argument 3 has type 'int'

Rather than tweak the format string, use the new assert() helper instead.

net/eth.c: throw BUG for eth_get_dev_by_name(NULL)

2011-09-09T21:58:47+00:00

eth_get_dev_by_name() is not safe to use for devname being NULL
as it uses strcmp. This patch makes it fail with a BUG().

Correct call to eth_write_hwaddr()

2011-09-05T14:06:06+00:00

This fixes "Warning: failed to set MAC address" on platforms which rely on
an 'ethaddr' environment variable to set the MAC address.

This bug was introduced by this commit:

Add Ethernet hardware MAC address framework to usbnet

2011-08-08T19:05:23+00:00

Built-in Ethernet adapters support setting the mac address by means of a
ethaddr environment variable for each interface (ethaddr, eth1addr, eth2addr).

This adds similar support to the USB network side, using the names
usbethaddr, usbeth1addr, etc. They are kept separate since we don't want
a USB device taking the MAC address of a built-in device or vice versa.

net/eth.c: drop obsolete at91rm9200 support

2011-08-03T11:00:56+00:00

All available at91rm9200 boards have migrated to ar920t/at91 and
therefore to CONFIG_NET_MULTI.
The obsolete at91rm9200_miiphy_initialize() was removed in "ARM: remove
obsolete at91rm9200".

Create PHY Lib for U-Boot

2011-04-20T20:09:19+00:00

Extends the mii_dev structure to participate in a full-blown MDIO and
PHY driver scheme.  The mii_dev structure and miiphy calls are modified
in such a way to allow the original mii command and miiphy
infrastructure to work as before, but also to support a new set of APIs
which allow (among other things) sharing of PHY driver code and 10G support

The mii command will continue to support normal PHY management functions
(Clause 22 of 802.3), but will not be changed to support 10G
(Clause 45).

The basic design is similar to PHY Lib from Linux, but simplified for
U-Boot's network and driver infrastructure.

We now have MDIO drivers and PHY drivers

An MDIO driver provides:
read
write
reset

A PHY driver provides:
(optionally): probe
config - initial setup, starting of auto-negotiation
startup - waiting for AN, and reading link state
shutdown - any cleanup needed

The ethernet drivers interact with the PHY Lib using these functions:
phy_connect()
phy_config()
phy_startup()
phy_shutdown()

Each PHY driver can be configured separately, or all at once using
config_phylib_all_drivers.h (added in the patch which adds the drivers)

We also provide generic drivers for Clause 22 (10/100/1000), and
Clause 45 (10G) PHYs.

We also implement phy_reset(), and call it in phy_connect(). Because
phy_reset() is essentially the same as miiphy_reset, but:
a) must support 10G PHYs, and
b) should use the phylib primitives,

we implement miiphy_reset, using phy_reset(), but only when
CONFIG_PHYLIB is set. Otherwise, we just use the old version. In this
way, we save on compile size, even if we don't manage to save code size.

Add USB host ethernet adapter support

2011-02-19T19:32:36+00:00

This adds support for using USB Ethernet dongles in host mode. This is just
the framework - drivers will come later. A new config option called
CONFIG_USB_HOST_ETHER can be defined in board config files to switch this
on.

The was originally written by NVIDIA and was cleaned up for release by the
Chromium authors.

Net: clarify board/cpu_eth_init calls

2010-11-14T23:01:15+00:00

This has always been confusing, and the idea of these functions returning the
number of interfaces initialized was half-baked and ultimately pointless.
Instead, act more like regular functions and return < 0 on failure, >= 0 on
success.

This change shouldn't break anything.
