net: Stop including NFS overhead in defragment max

2016-08-22T19:20:08+00:00

At least on bfin, this "specimen" is actually allocated in the BSS and
wastes lots of memory in already tight memory conditions.

Also, with the introduction of NFSv3 support, this waste got
substantially larger.

Just remove it. If a board needs a specific different defragment size,
that board can override this setting.

efi_loader: Add network access support

2016-05-27T14:01:10+00:00

We can now successfully boot EFI applications from disk, but users
may want to also run them from a PXE setup.

This patch implements rudimentary network support, allowing a payload
to send and receive network packets.

With this patch, I was able to successfully run grub2 with network
access inside of QEMU's -M xlnx-ep108.

net: Fix delay in net_retry test

2016-01-07T19:18:58+00:00

Introduced in 45b4773 (net/arp: account for ARP delay, avoid duplicate packets on timeout)

Check the arp timeout and adjust the timeout start time before the call
to eth_recv() so that the sandbox driver has the opportunity to adjust
the sandbox timer after the new start time has been recorded.

Also, change the adjustment amount by 11 seconds instead of exactly the
10 seconds that the ping timout is expecting since the timeout check is
looking for the time elapsed to be greater than but not equal to the
specified delay.

Move console definitions into a new console.h file

2015-11-20T03:27:50+00:00

The console includes a global variable and several functions that are only
used by a small subset of U-Boot files. Before adding more functions, move
the definitions into their own header file.

net: Increase the size of the net_boot_file_name buffer

2015-10-29T19:05:47+00:00

The net_boot_file_name buffer is used as storage for the bootfilename
command line argument to network boot commands such as tftp and nfs.

Increase the size of this buffer to 1024 bytes as the current size of
128 bytes is restrictive for arbitrary paths on the server.

net/arp: account for ARP delay, avoid duplicate packets on timeout

2015-10-28T19:57:37+00:00

eth_rx() in the main reception loop may trigger sending a packet which
is already timed out (or will immediately) upon reception of an ARP reply.
As long as the ARP reply is pending, the timeout handler of a packet
should be postponed.
Happens on TFTP with bad network (e.g. WLAN).

net: tftp: Move tftp.h file from ./net to ./include/net

2015-09-07T11:41:04+00:00

This change gives the ability to reuse the  header file by other
subsystems (like e.g. dfu).

Without this change compilation error emerges for the legacy update.c file.

net: Return -EINTR when ctrl+c is pressed

2015-08-21T21:32:05+00:00

Current behavior is that if CTRL+C is pressed command returns 0 that was
successful which is not correct behavior.
The easiest test case is "tftpboot 80000 uImage && echo yes"
and press CTRL+C. Then the second command is called which is incorrect.

Error log:

net: Use env callbacks for net variables

2015-05-21T13:13:20+00:00

Instead of checking for changes to the env each time we enter the
net_loop, use the env callbacks to update the values of the variables.
Don't update the variables when the source was programmatic, since the
variables were the source of the new value.
