2014-05-12net: rename and refactor eth_rand_ethaddr() functionMasahiro Yamada
Some functions in include/net.h are ported from include/linux/etherdevice.h of Linux Kernel. For ex. is_zero_ether_addr() is_multicast_ether_addr() is_broadcast_ether_addr() is_valid_ether_addr(); So, we should use the same function name as that of Linux Kernel, eth_rand_addr(), for consistency. Besides, eth_rand_addr() has been implemented as an inline function. So it should not be surrounded by #ifdef CONFIG_RANDOM_MACADDR.

2014-02-07net: execute "miiphy_init" if CONFIG_PHYLIB definedAlexey Brodkin
In "common/Makefile" "miiphyutil.o" gets built if any of the following items enabled: * CONFIG_PHYLIB * CONFIG_MII * CONFIG_CMD_MII So it's possible to not define CONFIG_MII or CONFIG_CMD_MII and still use functions like "miiphy_get_dev_by_name". In its turn "miiphy_get_dev_by_name" traverses "mii_devs" list which is not initialized because "miiphy_init" never got called.

2012-09-24net: Improve the speed of netconsoleJoe Hershberger
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.

2012-09-24api: net: fix length check in eth_receive()Michael Walle
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.

2012-04-03net/eth.c: fix eth_write_hwaddr() to use dev->enetaddr as fall backEric Miao
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.

2012-03-18net/miiphy/serial: drop duplicate "NAMESIZE" defineMike Frysinger
A few subsystems are using the same define "NAMESIZE". This has been working so far because they define it to the same number. However, I want to change the size of eth_device's NAMESIZE, so rather than tweak the define names, simply drop references to it. Almost no one does, and the handful that do can easily be changed to a sizeof(). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Instead of counting the device index everytime a functions needs it, store it in the eth_device struct. eth_register() keeps track of the indices and updates the device's index number.

2011-04-20Create PHY Lib for U-BootAndy Fleming
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.
