* net: defragment IP packetsAlessandro Rubini2009-08-25-5/+183
| | | | | | | | | | | | | | | | | The defragmenting code is enabled by CONFIG_IP_DEFRAG; the code is useful for TFTP and NFS transfers. The user can specify the maximum defragmented payload as CONFIG_NET_MAXDEFRAG (default 16k). Since NFS has a bigger per-packet overhead than TFTP, the static reassembly buffer can hold CONFIG_NET_MAXDEFRAG + the NFS overhead. The packet buffer is used as an array of "hole" structures, acting as a double-linked list. Each new fragment can split a hole in two, reduce a hole or fill a hole. No support is there for a fragment overlapping two diffrent holes (i.e., thre new fragment is across an already-received fragment).

* minor debug cleanups in ./netRobin Getz2009-08-07-56/+24
| | | | | | | | | | | | | | | Minor ./net cleanups - no functional changes - change #ifdef DEBUG printf(); #endif to just debug() - changed __FUNCTION__ to __func__ - got rid of extra whitespace between function and opening brace - removed unnecessary braces on if statements gcc dead code elimination should make this functionally/size equivalent when DEBUG is not defined. (confirmed on Blackfin, with gcc 4.3.3). Signed-off-by: Robin Getz <rgetz@blackfin.uclinux.org> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>
* Save server's MAC address in environmentRobin Getz2009-07-22-0/+9
| | | | | | | | | | | | | | | Linux's netconsole works much better when you can pass it the MAC address of the server. (otherwise it just uses broadcast, which everyone else on my network complains about :) This sets the env var "serveraddr" (to match ethaddr), so that you can pass it to linux with whatever bootargs you want to.... addnetconsole=set bootargs $(bootargs) netconsole=@$(ipaddr)/eth0,@$(serverip)/$(serveraddr) Signed-of-by: Robin Getz <rgetz@blackfin.uclinux.org> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>

| | | | | | | | | | Fixed the DHCP/BOOTP/RARP regression introduced in u-boot-2009.06 by initializing our IP addr to 0 in order to accept any IP addr assigned to us by the DHCP/BOOTP/RARP server.

* Add DNS supportRobin Getz2009-07-22-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On 04 Oct 2008 Pieter posted a dns implementation for U-Boot. http://www.mail-archive.com/u-boot-users@lists.sourceforge.net/msg10216.html > > DNS can be enabled by setting CFG_CMD_DNS. After performing a query, > the serverip environment var is updated. > > Probably there are some cosmetic issues with the patch. Unfortunatly I > do not have the time to correct these. So if anybody else likes DNS > support in U-Boot and has the time, feel free to patch it in the main tree. Here it is again - slightly modified & smaller: - update to 2009-06 (Pieter's patch was for U-Boot 1.2.0) - README.dns is added - syntax is changed (now takes a third option, the env var to store the result in) - add a random port() function in net.c - sort Makefile in ./net/Makefile - dns just returns unless a env var is given - run through checkpatch, and clean up style issues - remove packet from stack - cleaned up some comments - failure returns much faster (if server responds, don't wait for timeout) - use built in functions (memcpy) rather than byte copy.

* NetLoop initialization bugMichael Zaidman2009-04-19-59/+4
| | | | | | | | | | | | | | | | | | | | The patch fixes the bug of partial initialization of global network parameters. Upon u-boot's start up the first ping command causes a failure of the consequent TFTP command. It happens in the recently added mechanism of the NetLoop initialization where initialization of global network parameters is separated in the NetInitLoop routine which is called per env_id change. Thus, ping request will initialize the network parameters necessary for ping operation only, afterwards the env_changed_id will be set to the env_id that will prevent all following initialization requests from other protocols. The problem is that the initialized by ping subset of network parameters is not sufficient for other protocols and particularly for TFTP which requires the NetServerIp also.

* netloop: speed up NetLoopHeiko Schocher2009-02-22-59/+75
| | | | | | | | | | | | | | NetLoop polls every cycle with getenv some environment variables. This is horribly slow, especially when the environment is big.

| | | | | | | | | | | | | | | | | | Enforce millisecond semantics of the first argument to NetSetTimeout() -- the change is transparent for well-behaving boards (CFG_HZ == 1000 and get_timer() countiing in milliseconds). Rationale for this patch is to enable millisecond granularity for network-related timeouts, which is needed for the upcoming automatic software update feature.

* Get rid of annoying/superfluous bad-checksum warning messageRemy Bohmer2008-06-04-0/+4
| | | | | | | | | | | | | U-boot can complain a lot about 'checksum bad' when it is attached to the network. It is annoying for ordinary users who start to doubt the network connection in general when they see messages like this. This is caused by the routine NetCksumOk() which cannot handle IP-headers longer than 20 bytes. Those packages can be ignored anyway by U-boot, so we trash them now before checking the checksum.

* net: make ARP timeout configurableGuennadi Liakhovetski2008-04-28-6/+17
| | | | | | | | | | | | | | Currently the timeout waiting for an ARP reply is hard set to 5 seconds. On i.MX31ADS due to a hardware "strangeness" up to four first IP packets to the boards get lost, which typically are ARP replies. By configuring the timeout to a lower value we significantly improve the first network transfer time on this board. The timeout is specified in milliseconds, later internally it is converted to deciseconds, because it has to be converted to hardware ticks, and CFG_HZ ranges from 900 to 27000000 on different boards.

* Introduce new eth_receive routineRafal Jaworowski2008-01-03-0/+10
| | | | | | | | | | | | | | The purpose of this routine is receiving a single network frame, outside of U-Boot's NetLoop(). Exporting it to standalone programs that run on top of U-Boot will let them utilise networking facilities. For sending a raw frame the already existing eth_send() can be used. The direct consumer of this routine is the newly introduced API layer for external applications (enabled with CONFIG_API).

This permits the ping command to test the phy interface when the phy is put in loopback mode (typically by setting register 0 bit 14). It also allows the port to respond to an external ping when u-boot is processing some other net command (such as tftp). This is useful when tftp appears to hang.
