* dm: eth: Provide a way for drivers to manage packet buffersJoe Hershberger2015-04-18-1/+3
| | | | | | | | | | | | Some drivers need a chance to manage their receive buffers after the packet has been handled by the network stack. Add an operation that will allow the driver to be called in that case.

* net: Improve error handlingJoe Hershberger2015-04-18-8/+48
| | | | | | | | | | | | 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.

* dm: eth: Pass the packet pointer as a parameter to recvJoe Hershberger2015-04-18-1/+14
| | | | | | | | | | Stop forcing drivers to call net_process_received_packet() - formerly called NetReceive(). Now the uclass will handle calling the driver for each packet until the driver errors or has nothing to return. The uclass will then pass the good packets off to the network stack by calling net_process_received_packet(). Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>

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.

* 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.

* Create PHY Lib for U-BootAndy Fleming2011-04-20-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
