* | net: only use ethaddrs registered with device node on that deviceLucas Stach2018-11-081-0/+1
|/ | | | | | | | | | | | | | If an ethaddr is registered with a device node the ethid is set to 0 via the struct initialization. Now if a device without a node (for eaxample a USB network adapter) with ethid 0 looks up the ethaddr it will wrongly get that address assigned, as the ethid matches. Avoid this by setting the ethid to something that no device will ever use when the addr is registered via a device node.

* net: Add linuxdevname propertySascha Hauer2017-12-151-0/+2
| | | | | | | | | | | | | | | | | When you have a static network environment but more than one network device on your machine it is necessary to provide the <device> parameter to the ip parameter at kernel cmd line. The device name assigned by Linux cannot in general be predicted as it depends on driver bind order. This patch introduces a new property linux.devname to eth devices. The value is added to bootargs per interface and can be changed in env/network/INTF Based on patch by Gavin Schenk <g.schenk@eckelmann.de>. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* net: Provide new way to configure network devicesSascha Hauer2017-12-141-0/+15
| | | | | | | | | | | | | | | | | | | This provides a new way to configure network interfaces based on nvvars. A network interface can now be configured with variables in the nv.dev.<ethname>.* namespace. There is a new network device parameter "mode" which specifies the mode used to obtain IP settings. The mode can be "dhcp", "static" or "disabled": nv.dev.eth0.mode=dhcp (ipaddr, netmask are ignored in this setting) nv.dev.eth0.mode=static nv.dev.eth0.ipaddr=192.168.0.17 nv.dev.eth0.netmask=255.255.0.0 nv.dev.eth0.mode=disabled Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* net: Use a single gatewaySascha Hauer2017-12-011-1/+2
| | | | | | | | | | | | | | There is not much point in having a network device specific gateway. If barebox really is part of such a complicated network in which it needs multiple gateways, then we probably need a real routing table. Until this happens, a single gateway should be enough. This introduces global.net.gateway which holds the gateway ip. The previously used device specific <ethx>.gateway variables still exist, but are only aliases for the single gateway.

* net: introduce global.net.serverSascha Hauer2017-12-011-1/+3
| | | | | | | | | | | | The server to use is independent of the network device, there is not much point to make the server specific to a network device. This introduces global.net.server as the serverip which is used as standard NFS/tftp server. The previously used eth device specific parameters still exist, but are only aliases for the global single variable. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* net: add linux.bootarg parameter from ifup callEnrico Jorns2016-09-221-0/+2
| | | | | | | | | | | | | This sets a `ip=dhcp` or `ip=<clientip>:<serverip>:<gatewayip>:<netmaskip>::<iface>:` bootarg for the network device upon execution of 'ifup'. This is the only point where we can distinguish between a static ip and a dhcp-based network setup and thus set a valid bootarg options as it will be required for nfs boot, for example.

* net: eth: add name to struct eth_deviceSascha Hauer2016-07-141-5/+7
| | | | | | | | | Using dev_name often is not a good idea since it's a statically allocated string which gets overwritten by later calls to dev_name. Add a devname string to struct eth_device to have the name available for later use. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* net: eth: Fixup OF tree with registered MAC addresses tooTrent Piepho2015-10-221-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | The eth code registers an OF tree fixup that looks for any nodes in the Linux oftree that match eth devices loaded in barebox and sets the mac-address property in those nodes. The purpose is to pass MAC addresses to the Linux kernel for drivers that expect the MAC address to be in the device tree. If barebox does not have a driver for the network device, either because it has been disabled or because one does not exist, then the OF tree will not be fixed up to include a MAC address. The eth code also has a list of MAC addresses which board code has registered, usually done when it reads the address from an EEPROM or on-chip memory. If an eth device is created later in the boot, it will look here for an address. The registered MAC address list is not used for the OF tree fix up, and this patch changes that. This way barebox can place a MAC address in the device-tree without needing a driver for the network device.

* net: Allow to use multiple network interfaces at onceSascha Hauer2014-05-151-27/+31
| | | | | | | | | | | | | | | | In barebox network packets always go out at the current ethernet device and are expected to be received from the current interface. This has some side effects. When for example an NFS is mounted when one interface is active and the interface is changed afterwards the NFS packets leave the new interface, but the NFS server won't be reachable there. Instead of changing the whole network traffic to the current ethernet interface we now initialize a network connection with the current network interface, but then the connection will continue to use that interface even when the current interface is changed.
