2020-03-09phy: Add support for the NC-SI protocolSamuel Mendoza-Jonas
This introduces support for the NC-SI protocol, modelled as a phy driver for other ethernet drivers to consume. NC-SI (Network Controller Sideband Interface) is a protocol to manage a sideband connection to a proper network interface, for example a BMC (Baseboard Management Controller) sharing the NIC of the host system. Probing and configuration occurs by communicating with the "remote" NIC via NC-SI control frames (Ethernet header 0x88f8). This implementation is roughly based on the upstream Linux implementation[0], with a reduced feature set and an emphasis on getting a link up as fast as possible rather than probing the full possible topology of the bus. The current phy model relies on the network being "up", sending NC-SI command frames via net_send_packet() and receiving them from the net_loop() loop (added in a following patch). The ncsi-pkt.h header[1] is copied from the Linux kernel for consistent field definitions.

Peter originally sent a fix, but it breaks a number of other things. This addresses the original reported issue in a different way. That report was: > U-Boot has 1 common buffer to send Ethernet frames, pointed to by > net_tx_packet.

2018-07-02net: Prefer command line argumentsAlexander Graf
We can call commands like dhcp and bootp without arguments or with explicit command line arguments that really should tell the code where to look for files instead. Unfortunately, the current code simply overwrites command line arguments in the dhcp case with dhcp values. This patch allows the code to preserve the command line values if they were set on the command line. That way the semantics are slightly more intuitive. The reason this patch does that by introducing a new variable is that we can not rely on net_boot_file_name[0] being unset, as today it's completely legal to call "dhcp" and afterwards run "tftp" and expect the latter to repeat the same query as before. I would prefer not to break that behavior in case anyone relies on it. Signed-off-by: Alexander Graf <agraf@suse.de> Acked-by: Joe Hershberger <joe.hershberger@ni.com>
2018-07-02net: Add new wol command - Wake on LANLothar Felten
Add a new command 'wol': Wait for an incoming Wake-on-LAN packet or time out if no WoL packed is received. If the WoL packet contains a password, it is saved in the environment variable 'wolpassword' using the etherwake format (dot or colon separated decimals). Intended use case: a networked device should boot an alternate image. It's attached to a network on a client site, modifying the DHCP server configuration or setup of a tftp server is not allowed. After power on the device waits a few seconds for a WoL packet. If a packet is received, the device boots the alternate image. Otherwise it boots the default image. This method is a simple way to interact with a system via network even if only the MAC address is known. Tools to send WoL packets are available on all common platforms. Some Ethernet drivers seem to pad the incoming packet. The additional padding bytes might be recognized as Wake-on-LAN password bytes. By default enabled in pengwyn_defconfig.

2015-07-21dm: eth: Avoid blocking on packet receptionSimon Glass
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.
