| | | | | | | | | | | | | | | | The defaultenv-2 has ifup support as a shell script. This patch replaces it with a command which is more robust, can be called from C and now can also bring up all configured interfaces. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | If a network device has not been registered from the devicetree, we may still find it by its alias in the devicetree. This way also platform based network devices can obtain a valid MAC address in the devicetree.

* | net: Set mac-address propertySascha Hauer2013-06-051-0/+54
|/ | | | | | | | | | Linux normally has no idea how to retrieve MAC Addresses, but instead expects the MAC address in the devicetree. This patch adds the MAC address to the devicetree for Linux if we find a valid one in barebox. This mechanism is limited of course to devices barebox has a driver for and which are probed themselves from the devicetree. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* net: Add of_register_ethaddrSascha Hauer2013-05-211-12/+56
| | | | | | | | | | | | We already have a possibility to register a MAC address provider based on a ethernet device id. This adds a similar functionality for devices probed from devicetree. Code can register itself to be a MAC address provider for a certain devicetree node. This helps on i.MX to let the IIM unit provide a MAC address for the FEC.

* net: dhcp: Fix tftp servername handlingSascha Hauer2013-05-141-3/+6
| | | | | | | | | | | | | When the dhcp code discovered the tftp-server-name option it immediately tries to resolve the name. This can't succeed since the we are somewhere in the dhcp processing and the nameserver may not even be known. Fix this by resolving the name when dhcp is completed. While at it, do this in a way that net_set_serverip is only called when resolv() returns something useful. Otherwise we may end up overwriting a previously configured serverip which came from the bootp bp_siaddr field. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

This function is removed from the tree. Now callers of register_device have to clearly set the parent *before* registering a device.

* net phylib: Call phy_update_status when no link is presentSascha Hauer2012-12-081-1/+2
| | | | | | | | | | | | We call phy_update_status only once in 5 seconds. This makes sure we do not have great overhead when using ethernet devices. However, if phylib tells us the link is down anyway, there won't be ethernet transfers, so it doesn't hurt to call phy_update_status in this case. This makes sure we can use the ethernet device when the link comes up and do not have an additional 5 second penalty in this case. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
