Fix various code style issues in the lwIP code. Reported-by: Tom Rini <trini@konsulko.com> Signed-off-by: Jerome Forissier <jerome.forissier@linaro.org> Acked-by: Ilias Apalodimas <ilias.apalodimas@linaro.org>
2024-10-16net: lwip: add TFTP_BLOCKSIZEJerome Forissier
Add support for setting the TFTP block size. The default value (1468) is fine for Ethernet and allows a better throughput than the TFTP default (512), if the server supports the blksize option of course. I tested this change with qemu_arm64_lwip_defconfig. The throughput is now 875 KiB/s vs. 313 KiB/s before. That is still a low number, but I think we can't expect more without implementing the windowsize option.

2024-10-16net: lwip: add TFTP support and tftpboot commandJerome Forissier
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}.

2024-10-16net: lwip: add DHCP support and dhcp commmandJerome Forissier
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.
