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

2015-07-21T23:39:41Z

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

2015-07-21T23:39:40Z

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. Signed-off-by: Simon Glass

net: Handle ethaddr changes as an env callback

2015-05-21T13:16:16Z

When the ethaddr is changed in the env, update the device pdata at the same time (only if it is probed for the DM case; only if registered for the non-DM case). Again this gets us closer to completely non-polled env needed to simplify the net_loop. This requires that the NET feature select the REGEX feature. Signed-off-by: Joe Hershberger

net: Remove duplicate bootfile syncing functionality

2015-05-21T13:13:20Z

The bootfile env var is already kept up to date by the callback in net.c so there is no need to poll it too. Signed-off-by: Joe Hershberger

net: Implement random ethaddr fallback in eth.c

2015-05-19T18:33:21Z

Implement the random ethaddr fallback in eth.c so it is in a common place and not reimplemented in each board or driver that wants this behavior. Signed-off-by: Joe Hershberger Reviewed-by: Simon Glass

net: Update hardware MAC address if it changes in env

2015-05-19T18:33:21Z

When the ethaddr changes in the env, the hardware should also be updated so that MAC filtering will work properly without resetting U-Boot. Also remove the manual calls to set the hwaddr that was included in a few drivers as a result of the framework not doing it.

dm: net: Use existing Ethernet init for driver model

2015-04-18T17:11:36Z

At present even with driver model is used there is still much manual init of related devices: PHY, environment and board init. Until these requirements are dealt with in another way we need to keep them around. Break out the init portion of the legacy eth_initialize() into a separate function and call it from both the legacy and driver model eth_initialize() functions.

net: cosmetic: Name ethaddr variables consistently

Use "_ethaddr" at the end of variables and drop CamelCase. Make constant values actually 'const'. Signed-off-by: Joe Hershberger Acked-by: Simon Glass
