2009-05-15netloop: updates for NetLoopHeiko Schocher
Fix some issues introduced from commit: 2f70c49e5b9813635ad73666aa30f304c7fdeda9 suggested by Mike Frysinger. - added some comment for the env_id variable in common_cmd_nvedit.c - moved some variables in fn scope instead of file scope - NetInitLoop now static void Signed-off-by: Heiko Schocher <hs@denx.de> Acked-by: Ben Warren <biggerbadderben@gmail.com>
2009-04-20NetLoop initialization bugMichael Zaidman
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.

2009-03-20convert print_IPaddr() to %pI4Mike Frysinger
Now that our printf functions support the %pI4 modifier like the kernel, let's drop the inflexible print_IPaddr() function and covert over to the %pI4 modifier. Signed-off-by: Mike Frysinger <vapier@gentoo.org> CC: Ben Warren <biggerbadderben@gmail.com>
2009-02-23netloop: speed up NetLoopHeiko Schocher
NetLoop polls every cycle with getenv some environment variables. This is horribly slow, especially when the environment is big. This patch reads only the environment variables in NetLoop, when they were changed. Also moved the init part of the NetLoop function in a seperate function.

2009-01-29Fix IP alignment problemOlav Morken
This patch removes volatile from: volatile IP_t *ip = (IP_t *)xip; Due to a bug, avr32-gcc will assume that ip is aligned on a word boundary when using volatile, which causes an exception since xip isn't aligned on a word boundary.

2008-10-18net: express the first argument to NetSetTimeout() in millisecondsBartlomiej Sieka
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. Summary of changes: - do not scale the first argument to NetSetTimeout() by CFG_HZ - change timeout values used in the networking code to milliseconds Signed-off-by: Rafal Czubak <rcz@semihalf.com> Signed-off-by: Bartlomiej Sieka <tur@semihalf.com> Signed-off-by: Ben Warren <biggerbadderben@gmail.com>

2008-06-05Get rid of annoying/superfluous bad-checksum warning messageRemy Bohmer
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.

2008-05-20Big white-space cleanup.Wolfgang Denk
This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>
2008-04-29net: make ARP timeout configurableGuennadi Liakhovetski
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.

2008-01-04net: Add CONFIG_NET_DO_NOT_TRY_ANOTHER optionMatthias Fuchs

2008-01-04Introduce new eth_receive routineRafal Jaworowski
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).

2007-03-07net - Support ping reply when processing net-loopEd Swarthout
Add ICMP_ECHO_REQUEST packet support by responding with a ICMP_ECHO_REPLY. 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.
