2018-07-26net: Consolidate the parsing of bootfileJoe Hershberger
The same basic parsing was implemented in tftp and nfs, so add a helper function to do the work once. Signed-off-by: Joe Hershberger <[email protected]>
2018-07-26net: When checking prerequisites, consider boot_file_nameJoe Hershberger
For net_boot_common, we allow the serverip to be specified as part of the boot file name. For net commands that require serverip, include that source as a valid specification of serverip. Signed-off-by: Joe Hershberger <[email protected]> Reviewed-by: Alexander Graf <[email protected]>
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 <[email protected]> Acked-by: Joe Hershberger <[email protected]>
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.

2015-09-29net: expose eth_is_active() function to test network device stateBernhard Nortmann
The previous eth_device struct returned by eth_get_dev() allowed code to directly query the state member field. However, with CONFIG_DM_ETH this data gets encapsulated (i.e. private), and eth_get_dev() returns a udevice struct 'abstraction' instead. This breaks legacy code relying on the former behaviour - e.g. netconsole. (see http://lists.denx.de/pipermail/u-boot/2015-June/216528.html) The patch introduces a method to retrieve the ethernet device state in a 'clean' and uniform way, supporting both legacy code and driver model. The new function eth_is_active() accepts a device struct pointer and tests it for ETH_STATE_ACTIVE.

2015-07-21net: Allow drivers to return -ENOSYS with the write_hwaddr() methodSimon Glass
Some drivers may want to implement this method for some of their devices but not for others. So it is not possible to just leave the operation out of the table.

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.
