net: uclass: Save generated ethernet MAC addresses to the environment

2022-01-11T09:33:42Z

When a MAC address is randomly generated we currently only update the appropriate data structure. For consistency and to re-align with historic usage, it should be also saved to the appropriate environment variable as well.

net: convert TFTP_TSIZE to proper Kconfig option

2021-06-09T01:38:51Z

TFTP transfer size can be used to re-size the TFTP progress bar on single line based on the server reported file size. The support for this has been around from 2019, but it was never converted to proper Kconfig. While adding this new Kconfig, enable it by default for OMAP2+ and K3 devices also.

Adds basic support for ProxyDHCP

2020-12-01T15:33:37Z

- 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 Signed-off-by: Lyle Franklin

net: add a generic udp protocol

2020-09-30T20:55:03Z

This commit adds a generic udp protocol framework in the network loop. So protocol based on udp may be implemented without modifying the network loop (for example custom wait magic packet). Signed-off-by: Philippe Reynes Reviewed-by: Simon Glass

net: tftp: Add client support for RFC 7440

2020-08-05T03:30:02Z

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. Signed-off-by: Ramon Fried Reviewed-by: Marek Vasut
