|/ | | | | | | | | | | | | | | | | | | | The commit commit be0404c21f22da2d736168b2e56a9ae583cc3e95 Author: Sascha Hauer <s.hauer@pengutronix.de> Date: Wed May 14 16:08:04 2014 +0200 net: Allow to use multiple network interfaces at once changes the eth_send() function: - return eth_current->send(eth_current, packet, length); + return edev->send(eth_current, packet, length); But we have to change the both eth_current occurrences to edev here!

* net: eth: Do not rely on CONFIG_PARAMETER to be enabledSascha Hauer2015-06-261-8/+19
| | | | | | | | | register_preset_mac_address only works when CONFIG_PARAMETER is enabled because otherwise dev_set_param is a no-op. Add a function to set the MAC address explicitly without the need of CONFIG_PARAMETER and use it where appropriate. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* eth: halt active ethernet device on unregisterSascha Hauer2015-04-281-0/+3

* net: Call edev->recv with correct eth_deviceSascha Hauer2014-09-171-1/+1
| | | | | | | | edev->recv has to be called with edev as argument, not eth_current. This fixes networking when multiple network devices are used and the current one is switched during runtime. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* net: take eth id from devicetree aliasSascha Hauer2014-05-151-2/+11

* 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.

* | 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.

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>

* | net eth: make edev->init optionalSascha Hauer2012-10-301-1/+2
|/ | | | | | | | | | edev->init is called at eth_register time unconditionally and is supposed to initialize the ethernet hardware. Since it's called unconditionally this could be done by the driver without having an additional hook. Some drivers need their initialization done earlier since they also register a mdiobus which does hardware accesses on registration time. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
