* net: Filter incoming netconsole packets by IPJoe Hershberger2012-09-24-1/+2
| | | | | | | Check the incoming packets' source IP address... if ncip isn't set to a broadcast address, only listen to the client at ncip. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
* net: Improve the speed of netconsoleJoe Hershberger2012-09-24-1/+41
| | | | | | | | | | | | | | | | | | | Previously u-boot would initialize the network interface for every network operation and then shut it down again. This makes sense for most operations where the network in not known to be needed soon after the operation is complete. In the case of netconsole, it will use the network for every interaction with the shell or every printf. This means that the network is being reinitialized very often. On many devices, this intialization is very slow. This patch checks for consecutive netconsole actions and leaves the ethernet hardware initialized between them. It will still behave the same old way for all other network operations and any time another network operation happens between netconsole operations.

* net: Allow filtering on debug traces in the net subsystemJoe Hershberger2012-05-23-0/+5
| | | | | | | | | | | | Add several levels of DEBUG prints so that you can limit the noise to the severety of your problem. DEBUG_LL_STATE = Link local state machine changes DEBUG_DEV_PKT = Packets or info directed to the device DEBUG_NET_PKT = Packets on info on the network at large DEBUG_INT_STATE = Internal network state changes Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>

* net: Don't copy every packet that waits for an ARPJoe Hershberger2012-05-23-3/+3
| | | | | | | | | Use the NetArpTxPacket for the ARP packet, not to hold what used to be in NetTxPacket. This saves a copy and makes the code easier to understand. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org>
* net: Fix net buffer initializationJoe Hershberger2012-05-23-0/+1

* net: Add net_update_ether() to handle ARP and Ping repliesJoe Hershberger2012-05-23-0/+1

* net/miiphy/serial: drop duplicate "NAMESIZE" defineMike Frysinger2012-03-18-3/+1
| | | | | | | | | | A few subsystems are using the same define "NAMESIZE". This has been working so far because they define it to the same number. However, I want to change the size of eth_device's NAMESIZE, so rather than tweak the define names, simply drop references to it. Almost no one does, and the handful that do can easily be changed to a sizeof(). Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* net: introduce per device indexMichael Walle2011-12-20-0/+1
| | | | | | | | | | | | | | | | Instead of counting the device index everytime a functions needs it, store it in the eth_device struct. eth_register() keeps track of the indices and updates the device's index number. This simplifies some functions in net/eth.c. Additionally, a network driver can now query its index, eg. to get the correct environment ethaddr name.

* net: Make sure IPaddr_t is 32 bits in sizeMatthias Weisser2011-12-06-1/+2
| | | | | | | | | | | When building u-boot as 64 bit application (e.g. sandbox) ulong might be 64 bits in size. This breaks network code as IPaddr_t is 64 bytes in size then and an IPv4 address is 32 bits in size. This patch makes sure that IPaddr_t is always 32 bits in size. Also some warnings introduced by this patch are fixed. Signed-off-by: Matthias Weisser <weisserm@arcor.de> Acked-by: Mike Frysinger <vapier@gentoo.org>
* net: Export auto_load, use it in rarpSimon Glass2011-10-27-0/+6
| | | | | | | | | | | The rarp code includes another instance of the auto_load logic, so call what is now net_auto_load() instead. This also fixes an incorrect call to TftpStart() which was never seen since apparently no boards enable rarp.

* net: tftpput: Rename TFTP to TFTPGETSimon Glass2011-10-26-3/+5
| | | | | | | | This is a better name for this protocol. Also remove the typedef to keep checkpatch happy, and move zeroing of NetBootFileXferSize a little earlier since TFTPPUT will need to change this. Signed-off-by: Simon Glass <sjg@chromium.org>
* net: tftpput: Add support for receiving ICMP packetsSimon Glass2011-10-26-0/+19
| | | | | | | | | | ICMP packets can tell you when there is no server at the other end. It is useful for tftp to figure this out, so that a quick error can be displayed, rather than pointlessly retrying. This adds an ICMP packet handler to the net interface. Signed-off-by: Simon Glass <sjg@chromium.org>
* net: drop !NET_MULTI codeMike Frysinger2011-10-05-40/+0
| | | | | | | | | | | This is long over due. All but two net drivers have been converted, but those have now been dropped. The only thing left to do is actually delete all references to NET_MULTI and code that is compiled when that is not defined. So here we scrub the core code.

* Add Ethernet hardware MAC address framework to usbnetSimon Glass2011-08-08-1/+24
| | | | | | | | | | | | Built-in Ethernet adapters support setting the mac address by means of a ethaddr environment variable for each interface (ethaddr, eth1addr, eth2addr). This adds similar support to the USB network side, using the names usbethaddr, usbeth1addr, etc. They are kept separate since we don't want a USB device taking the MAC address of a built-in device or vice versa.

After all network devices have been initialized and the proper MAC address for each has been determined, make a device driver call to program the address into the device.

* Make getenv_IPaddr() globalDirk Behme2010-01-17-3/+0
| | | | | | | | | | | | | | | | | | | There are boards out there that do not have network support in U-Boot (CONFIG_CMD_NET not set), but they do so in Linux. This makes it desirable to be able to port network configuration (like the IP address) to the Linux kernel. We should not make the passing of the IP configuration to Linux dependent on U-Boot features / settings. For this, make getenv_IPaddr() global. This fixes build error u-boot/lib_xxx/board.c:360: undefined reference to `getenv_IPaddr' on various architectures.

* net: sync env ethaddr to device enetaddr in eth_init()Mike Frysinger2009-08-07-1/+1
| | | | | | | | | | | | In the previous enetaddr refactoring, the assumption with commit 56b555a644 was that the eth layer would handle the env -> device enetaddr syncing. This was not the case as eth_initialize() is called only once and the sync occurs there. So make sure the eth_init() function does the env -> device sync with every network init.
