* net: eth: Check return value in various placesBin Meng2015-10-29-18/+25
| | | | | | | | | | | eth_get_dev() can return NULL which means device_probe() fails for that ethernet device. Add return value check in various places or U-Boot will crash due to NULL pointer access. With this commit, 'dm_test_eth_act' test case passes.

* net: eth: Clear MAC address in eth_pre_remove()Bin Meng2015-10-29-0/+5
| | | | | | | | | | | platdata->enetaddr was assigned to a value in dev_probe() last time. If we don't clear it, for dev_probe() at the second time, dm eth will end up treating it as a MAC address from ROM no matter where it came from originally (maybe env, ROM, or even random). Fix this by clearing platdata->enetaddr when removing an Ethernet device. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Joe Hershberger <joe.hershberger@ni.com>

* net: expose eth_is_active() function to test network device stateBernhard Nortmann2015-09-29-1/+17
| | | | | | | | | | | | | | | | | | | | 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.

* net: Allow drivers to return -ENOSYS with the write_hwaddr() methodSimon Glass2015-07-21-0/+6
| | | | | | | | | | | | 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 receptionSimon Glass2015-07-21-1/+4
| | | | | | | | | | | | | | | | | | | | 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.

* net: Handle ethaddr changes as an env callbackJoe Hershberger2015-05-21-43/+60
| | | | | | | | | | | 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.

* net: Improve the speed of netconsoleJoe Hershberger2012-09-24-6/+2
| | | | | | | | | | | | | | | | | | | Previously u-boot would initialize the network interface for every network operation and then shut it down again. This makes sense for most operations where the network in not known to be needed soon after the operation is complete. In the case of netconsole, it will use the network for every interaction with the shell or every printf. This means that the network is being reinitialized very often. On many devices, this intialization is very slow. This patch checks for consecutive netconsole actions and leaves the ethernet hardware initialized between them. It will still behave the same old way for all other network operations and any time another network operation happens between netconsole operations.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Ignore the return value of eth_getenv_enetaddr_by_index(), and if it fails, fall back to use dev->enetaddr, which could be filled up by the ethernet device driver: With the current code, introduced with below commit, eth_write_hwaddr() will fail immediately if there is no eth<n>addr in the environment variables. However, e.g. for an overo based product that uses the SMSC911x ethernet chip (with the MAC address set via EEPROM connected to the SMSC911x chip), the MAC address is still OK. On mx28 boards that are depending on the OCOTP bits to set the MAC address (like the Denx m28 board), the OCOTP bits should be used instead of failing on the environment variables. Actually, this was the original behavior, and was later changed by commit 7616e7850804c7c69e0a22c179dfcba9e8f3f587.
