net: expose eth_is_active() function to test network device state

2015-09-30T02:54:45+00:00

The previous eth_device struct returned by eth_get_dev() allowed
code to directly query the state member field. However, with
CONFIG_DM_ETH this data gets encapsulated (i.e. private), and
eth_get_dev() returns a udevice struct 'abstraction' instead.

This breaks legacy code relying on the former behaviour - e.g.
netconsole.
(see http://lists.denx.de/pipermail/u-boot/2015-June/216528.html)

The patch introduces a method to retrieve the ethernet device
state in a 'clean' and uniform way, supporting both legacy code
and driver model. The new function eth_is_active() accepts a
device struct pointer and tests it for ETH_STATE_ACTIVE.

update: tftp: dfu: Extend update_tftp() function to support DFU

2015-09-07T11:41:05+00:00

This code allows using DFU defined mediums for storing data received via
TFTP protocol.

It reuses and preserves functionality of legacy code at common/update.c.

The update_tftp() function now accepts parameters - namely medium device
name and its number (e.g. mmc 1).

Without this information passed old behavior is preserved.

net: Allow drivers to return -ENOSYS with the write_hwaddr() method

2015-07-21T23:39:41+00:00

Some drivers may want to implement this method for some of their devices but
not for others. So it is not possible to just leave the operation out of
the table. Drivers could get around this by masquerading as two separate
drivers but that seems unpleasant.

Allow the driver to return an error when it does not want to process the
write_hwaddr() method.

dm: eth: Avoid blocking on packet reception

2015-07-21T23:39:40+00:00

Some devices can take a long time to work out whether they have a new packet
or now. For example the ASIX USB Ethernet dongle can take 5 seconds to do
this, since it waits until it gets a new packet on the wire before allowing
the USB bulk read packet to be submitted.

At present with driver mode the Ethernet receive code reads 32 packets. This
can take a very long time if we must wait for all 32 packets. The old code
(before driver model) worked by reading a single set of packets from the USB
device, then processing all the packets with in. It would be nice to use
the same behaviour with driver model.

Add a flag to the receive method which indicates that the driver should try
to find a packet if available, by consulting the hardware. When the flag is
not set, it should just return any packet data it has already received. If
there is none, it should return -EAGAIN so that the loop will terminate.

dm: net: Adjust PHY interface to work with CONFIG_DM_ETH

2015-04-18T17:11:36+00:00

When driver model is used for Ethernet a few functions are passed a udevice
instead of an eth_device. Also add a function to find a PHY type given its
name. This will be used to decode the device tree node.

Finally, put a phy_interface field in struct eth_pdata since this is an
important part of the platform data for Ethernet.

net: Fix incorrect DHCP/BOOTP packets on 64-bit systems

2015-04-18T17:11:35+00:00

This commit fixes incorrect DHCP/BOOTP packet layout caused by
'ulong' type size difference on 64 and 32-bit architectures.
It also renames NetReadLong()/NetCopyLong() to
net_read_u32/net_copy_u32() accordingly.
