net: Make NET imply NETDEVICES

Normally, when NET is enabled, CMD_NET will then be enabled and in turn
NETDEVICES will (likely) be enabled via imply. However, if we disable
CMDLINE in a defconfig we now no longer get CMD_NET enabling NETDEVICES
for us. This suggestion (as an imply is) really isn't about the network
commands but network itself and is a legacy of how intertwined
NET/CMD_NET were historically. Move this over to the NET entry instead
where it is a more logical fit.

Adds basic support for ProxyDHCP

- ProxyDHCP allows a second DHCP server to exist alongside your main
DHCP server and supply additional BOOTP related options
- When u-boot sends out a DHCP request, the real DHCP server will
respond with a normal response containing the new client IP address
while simultaneously the ProxyDHCP server will respond with a blank
client IP address and a `bootfile` option
- This patch adds CONFIG_SERVERIP_FROM_PROXYDHCP (default false) to
enable this behavior and CONFIG_SERVERIP_FROM_PROXYDHCP_DELAY_MS
(default 100) which tells u-boot to wait additional time after
receiving the main DHCP response to give the ProxyDHCP response time
to arrive
- The PXE spec for ProxyDHCP is more complicated than the solution
added here as diagramed on page 16:
http://www.pix.net/software/pxeboot/archive/pxespec.pdf:

```
DHCP Discover will be retried four times. The four timeouts are 4, 8, 16
and 32 seconds respectively. If a DHCPOFFER is received without an Option

net: tftp: Add client support for RFC 7440

Add support for RFC 7440: "TFTP Windowsize Option".

This optional feature allows the client and server
to negotiate a window size of consecutive blocks to send as an
alternative for replacing the single-block lockstep schema.

windowsize can be defined statically during compilation by
setting CONFIG_TFTP_WINDOWSIZE, or defined in runtime by
setting an environment variable: "tftpwindowsize"
If not defined, the windowsize is set to 1, meaning that it
behaves as it was never defined.

Choosing the appropriate windowsize depends on the specific
network topology, underlying NIC.
You should test various windowsize scenarios and see which
best work for you.

Setting a windowsize too big can actually decreases performance.

net: tftp: Fix too small block size

Commit b618b3707633 ("net: Convert CONFIG_TFTP_BLOCKSIZE to Kconfig")
accidentally set the default *option* TFTP block size to 512 bytes, even
though the comment in the code says that this is a terrible choice. Most
boards didn't define the symbol before, so they got the default block size
of 1468 bytes before, but now use 512 bytes, which is also the fallback.
This leads to both abysmal performance and a lot of hashes printed
on the screen (one character for every 5K), which is both annoying and
slow over serial links.

Set the default block size in Kconfig back to the value it had before.

This improves TFTP performance from 2.8 MB/s to 6.9 MB/s on a Pine64.

Commit b618b3707633 ("net: Convert CONFIG_TFTP_BLOCKSIZE to Kconfig")
accidentally set the default *option* TFTP block size to 512 bytes, even
though the comment in the code says that this is a terrible choice. Most
boards didn't define the symbol before, so they got the default block size
of 1468 bytes before, but now use 512 bytes, which is also the fallback.
This leads to both abysmal performance and a lot of hashes printed
on the screen (one character for every 5K), which is both annoying and
slow over serial links.

Set the default block size in Kconfig back to the value it had before.

This improves TFTP performance from 2.8 MB/s to 6.9 MB/s on a Pine64.

Adds basic support for ProxyDHCP

- ProxyDHCP allows a second DHCP server to exist alongside your main
DHCP server and supply additional BOOTP related options
- When u-boot sends out a DHCP request, the real DHCP server will
respond with a normal response containing the new client IP address
while simultaneously the ProxyDHCP server will respond with a blank
client IP address and a `bootfile` option
- This patch adds CONFIG_SERVERIP_FROM_PROXYDHCP (default false) to
enable this behavior and CONFIG_SERVERIP_FROM_PROXYDHCP_DELAY_MS
(default 100) which tells u-boot to wait additional time after
receiving the main DHCP response to give the ProxyDHCP response time
to arrive
- The PXE spec for ProxyDHCP is more complicated than the solution
added here as diagramed on page 16:
http://www.pix.net/software/pxeboot/archive/pxespec.pdf:

```
DHCP Discover will be retried four times. The four timeouts are 4, 8, 16
and 32 seconds respectively. If a DHCPOFFER is received without an Option
timeouts in an attempt to receive a PXE response.
```

- Adding a simple delay worked for my purposes but let me know if a
more robust solution is required

net: tftp: Add client support for RFC 7440

Add support for RFC 7440: "TFTP Windowsize Option".

This optional feature allows the client and server
to negotiate a window size of consecutive blocks to send as an
alternative for replacing the single-block lockstep schema.

windowsize can be defined statically during compilation by
setting CONFIG_TFTP_WINDOWSIZE, or defined in runtime by
setting an environment variable: "tftpwindowsize"
If not defined, the windowsize is set to 1, meaning that it
behaves as it was never defined.

Choosing the appropriate windowsize depends on the specific
network topology, underlying NIC.
You should test various windowsize scenarios and see which
best work for you.

Setting a windowsize too big can actually decreases performance.

Adds basic support for ProxyDHCP

- ProxyDHCP allows a second DHCP server to exist alongside your main
DHCP server and supply additional BOOTP related options
- When u-boot sends out a DHCP request, the real DHCP server will
respond with a normal response containing the new client IP address
while simultaneously the ProxyDHCP server will respond with a blank
client IP address and a `bootfile` option
- This patch adds CONFIG_SERVERIP_FROM_PROXYDHCP (default false) to
enable this behavior and CONFIG_SERVERIP_FROM_PROXYDHCP_DELAY_MS
(default 100) which tells u-boot to wait additional time after
receiving the main DHCP response to give the ProxyDHCP response time
to arrive
- The PXE spec for ProxyDHCP is more complicated than the solution
added here as diagramed on page 16:
http://www.pix.net/software/pxeboot/archive/pxespec.pdf:

```
DHCP Discover will be retried four times. The four timeouts are 4, 8, 16
and 32 seconds respectively. If a DHCPOFFER is received without an Option
timeouts in an attempt to receive a PXE response.
```

- Adding a simple delay worked for my purposes but let me know if a
more robust solution is required

net: tftp: Add client support for RFC 7440

Add support for RFC 7440: "TFTP Windowsize Option".

This optional feature allows the client and server
to negotiate a window size of consecutive blocks to send as an
alternative for replacing the single-block lockstep schema.

windowsize can be defined statically during compilation by
setting CONFIG_TFTP_WINDOWSIZE, or defined in runtime by
setting an environment variable: "tftpwindowsize"
If not defined, the windowsize is set to 1, meaning that it
behaves as it was never defined.

Choosing the appropriate windowsize depends on the specific
network topology, underlying NIC.
You should test various windowsize scenarios and see which
best work for you.

Setting a windowsize too big can actually decreases performance.

net: tftp: Fix too small block size

Commit b618b3707633 ("net: Convert CONFIG_TFTP_BLOCKSIZE to Kconfig")
accidentally set the default *option* TFTP block size to 512 bytes, even
though the comment in the code says that this is a terrible choice. Most
boards didn't define the symbol before, so they got the default block size
of 1468 bytes before, but now use 512 bytes, which is also the fallback.
This leads to both abysmal performance and a lot of hashes printed
on the screen (one character for every 5K), which is both annoying and
slow over serial links.

Set the default block size in Kconfig back to the value it had before.

This improves TFTP performance from 2.8 MB/s to 6.9 MB/s on a Pine64.

Adds basic support for ProxyDHCP

- ProxyDHCP allows a second DHCP server to exist alongside your main
DHCP server and supply additional BOOTP related options
- When u-boot sends out a DHCP request, the real DHCP server will
respond with a normal response containing the new client IP address
while simultaneously the ProxyDHCP server will respond with a blank
client IP address and a `bootfile` option
- This patch adds CONFIG_SERVERIP_FROM_PROXYDHCP (default false) to
enable this behavior and CONFIG_SERVERIP_FROM_PROXYDHCP_DELAY_MS
(default 100) which tells u-boot to wait additional time after
receiving the main DHCP response to give the ProxyDHCP response time
to arrive
- The PXE spec for ProxyDHCP is more complicated than the solution
added here as diagramed on page 16:
http://www.pix.net/software/pxeboot/archive/pxespec.pdf:

```
DHCP Discover will be retried four times. The four timeouts are 4, 8, 16
and 32 seconds respectively. If a DHCPOFFER is received without an Option
timeouts in an attempt to receive a PXE response.
```

- Adding a simple delay worked for my purposes but let me know if a
more robust solution is required

This optional feature allows the client and server

alternative for replacing the single-block lockstep schema.

windowsize can be defined statically during compilation by
setting CONFIG_TFTP_WINDOWSIZE, or defined in runtime by
setting an environment variable: "tftpwindowsize"
If not defined, the windowsize is set to 1, meaning that it
behaves as it was never defined.

Choosing the appropriate windowsize depends on the specific

You should test various windowsize scenarios and see which
best work for you.

Setting a windowsize too big can actually decreases performance.

accidentally set the default *option* TFTP block size to 512 bytes, even
though the comment in the code says that this is a terrible choice. Most
boards didn't define the symbol before, so they got the default block size
of 1468 bytes before, but now use 512 bytes, which is also the fallback.
This leads to both abysmal performance and a lot of hashes printed

slow over serial links.

Set the default block size in Kconfig back to the value it had before.

net: Move the VCI and client arch values to Kconfig

We have a bunch of boards that define their vendor class identifier and

to the generic Kconfig options.

We're missing the distinction between i386 and x86_64, as I couldn't find
any config variable that would tell us the difference. Is that really important
to people? I guess not, so I left it out.

net: TFTP: variables cleanup and addition

TFTP source and destination port variable names are
'tftpsrcp' and 'tftpdstp' in the code, but 'tftpsrcport'
and 'tftpdstport' in the README file. Fix the README.

Add environment variable 'tftptimeoutcountmax'. As per the
comments about the global variable tftp_timeout_count_max,
make sure tftptimeoutcountmax is nonnegative.

Introduce configuration option CONFIG_NET_TFTP_VARS,
which controls whether environment variables tftpblocksize,
tftptimeout, and tftptimoueoutcountmax are read by the TFTP
client code. CONFIG_NET_TFTP_VARS defaults to y but can be
set to n by targets with to tight size contraints.

Make bf527-ezkit set CONFIG_NET_TFTP_VARS to n to keep the
target size below limit.

net: support NETCONSOLE option via Kconfig

This patch introduces CONFIG_NETCONSOLE as an option to the
Kconfig system.

Joe Hershberger pointed out that it may not be entirely free of
problems, as many boards predating the driver model define this
symbol directly via include files. In case they're not properly
migrated, their NetConsole might 'vanish' if they start to use
CONFIG_NET or CONFIG_NETDEVICES.

Allow CONFIG_REGEX to be disabled when CONFIG_NET

Instead of selecting REGEX when NET is enabled, make it the default, but
allow boards that are tiny to disable it and lose functionality on all

net: Handle ethaddr changes as an env callback

When the ethaddr is changed in the env, update the device pdata at the
same time (only if it is probed for the DM case; only if registered for

env needed to simplify the net_loop.

This requires that the NET feature select the REGEX feature.
