* net: Use new checksum functionsSimon Glass2015-02-12-4/+0
| | | | | | | Drop the old checksum functions in favour of the new ones. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Joe Hershberger <joe.hershberger@ni.com>
* net: Add a separate file for IP checksummingSimon Glass2015-01-23-0/+30
| | | | | | | | Move the checksum code out into its own file so it can be used elsewhere. Also use a new version which supports a length which is not a multiple of 2 and add a new function to add two checksums. Signed-off-by: Simon Glass <sjg@chromium.org>

* SPDX License cleanup for LiMon imported filesWolfgang Denk2014-10-10-1/+1
| | | | | | | | | | | | | | | | A number of network related files were imported from the LiMon project; these contain a somewhat unclear license statement: Copyright 1994 - 2000 Neil Russell. (See License) I analyzed the source code of LiMon v1.4.2 which was used for this import. It does not contain any "License" file, but the top level directory contains a file "COPYING", which turns out to be GPL v2 of June 1991. So it is legitimate to conclude that the LiMon derived files are also to be released under GPLv2. Mark them as such. Signed-off-by: Wolfgang Denk <wd@denx.de>
* net: rename and refactor eth_rand_ethaddr() functionMasahiro Yamada2014-05-12-17/+19
| | | | | | | | | | | | | | | | | | | | Some functions in include/net.h are ported from include/linux/etherdevice.h of Linux Kernel. For ex. is_zero_ether_addr() is_multicast_ether_addr() is_broadcast_ether_addr() is_valid_ether_addr(); So, we should use the same function name as that of Linux Kernel, eth_rand_addr(), for consistency. Besides, eth_rand_addr() has been implemented as an inline function. So it should not be surrounded by #ifdef CONFIG_RANDOM_MACADDR.

* net: Fix mcast function pointer prototypeClaudiu Manoil2013-11-22-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the following compiler warnings when activating CONFIG_MCAST_TFTP: tsec.c: In function 'tsec_mcast_addr': tsec.c:130:2: warning: passing argument 2 of 'ether_crc' makes pointer from integer without a cast [enabled by default] In file included from /work/u-boot-net/include/common.h:874:0, from tsec.c:15: /work/u-boot-net/include/net.h:189:5: note: expected 'const unsigned char *' but argument is of type 'u8' tsec.c: In function 'tsec_initialize': tsec.c:646:13: warning: assignment from incompatible pointer type [enabled by default] eth.c: In function 'eth_mcast_join': eth.c:358:2: warning: passing argument 2 of 'eth_current->mcast' makes integer from pointer without a cast [enabled by default] eth.c:358:2: note: expected 'u32' but argument is of type 'u8 *' In the eth_mcast_join() implementation, eth_current->mcast() takes a u8 pointer to the multicast mac address and not a ip address value as implied by its prototype. Fix parameter type mismatch for tsec_macst_addr() (tsec.c): ether_crc() takes a u8 pointer not a u8 value. mcast() is given a u8 pointer to the multicats mac address. Update parameter type for the rest of mcast() instances. Signed-off-by: Claudiu Manoil <claudiu.manoil@freescale.com> Patch: 278989

* net: Filter incoming netconsole packets by IPJoe Hershberger2012-09-24-1/+2

* 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/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>

| | | | | | | | | | 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.

* 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.
