13e13f5867 net: lwip: dhcp: support arguments for TFTP file download
The dhcp command is supposed to have the following syntax as per
"help dhcp":

  dhcp [loadAddress] [[hostIPaddr:]bootfilename]

In other words, any arguments should be passed to an implicit
tftpboot command after the DHCP exchange has occurred.

Add the missing code to the lwIP version of do_dhcp().

8c95d84b39 net: lwip: fix dhcp_loop()
The local variables ipstr, maskstr and gwstr in static function
dhcp_loop() cannot be pointers to read-only data, since they may be
written to in case the device index is > 0. Therefore make them char
arrays allocated on the stack.

4d4d783812 net: lwip: add TFTP support and tftpboot command
Implement do_tftpb(). This implementation of the tftp command
supports an optional port number. For example:

 tftp 192.168.0.30:9069:file.bin

It also supports taking the server IP from ${tftpserverip} if
defined, before falling back to ${serverip}.

98ad145db6 net: lwip: add DHCP support and dhcp commmand
Add what it takes to enable NETDEVICES with NET_LWIP and enable DHCP as
well as the dhcp command. CMD_TFTPBOOT is selected by BOOTMETH_EFI due
to this code having an implicit dependency on do_tftpb().

Note that PXE is likely non-fonctional with NET_LWIP (or at least not
100% functional) because DHCP option 209 is not supported by the lwIP
library. Therefore, BOOTP_PXE_DHCP_OPTION cannot be enabled.
