* 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: Remove duplicate bootfile syncing functionalityJoe Hershberger2015-05-21-12/+0

* net: Update hardware MAC address if it changes in envJoe Hershberger2015-05-19-28/+48
| | | | | | | | | | | | 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 modelSimon Glass2015-04-18-37/+42
| | | | | | | | | | | | | 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.

| | | | | | | | | | | | Take a pass at plumbing errors through to the users of the network stack Currently only the start() function errors will be returned from NetLoop(). recv() tends not to have errors, so that is likely not worth adding. send() certainly can return errors, but this patch does not attempt to plumb them yet. halt() is not expected to error.

In its turn "miiphy_get_dev_by_name" traverses "mii_devs" list which is not initialized because "miiphy_init" never got called.

* 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.

* api: net: fix length check in eth_receive()Michael Walle2012-09-24-4/+1
| | | | | | | | | | | | | | | If the requested length is too small to hold the received packet, eth_receive() will return -1 and will leave the packet in the receive buffers. Instead of returning an error in this case, we return the first portion of the received packet and remove it from the receive buffers. This fixes FreeBSD's ubldr. Without this patch it will just stop receiving packets if the NIC receives more than PKTBUFSRX too large packets.

* net/eth.c: fix eth_write_hwaddr() to use dev->enetaddr as fall backEric Miao2012-04-03-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
