net: Move net command options to the cmd menu

2018-04-13T20:48:05+00:00

Options that controlled the tftp and bootp commands depended on their
commands, but lived in the net menu.

Move them so they are in a consistent location.

net: Make CMD_NET a menuconfig

2018-04-13T20:47:57+00:00

Previously, CMD_NET was an alias for 2 commands (bootp and tftpboot) and
they we not able to be disabled. Separate out those 2 commands and move
CMD_NET up to the menu level, which more accurately represents the code.

net: Move enetaddr env access code to env config instead of net config

2018-04-09T03:00:58+00:00

In order that we can use eth_env_* even when CONFIG_NET isn't set, move
these functions to environment code from net code.

This fixes failures such as:

  board/ti/am335x/built-in.o: In function `board_late_init':
  board/ti/am335x/board.c:752: undefined reference to `eth_env_set_enetaddr'
  u-boot/board/ti/am335x/board.c:766: undefined reference to `eth_env_set_enetaddr'

which caters for use cases such as:

commit f411b5cca48f ("board: am335x: Always set eth/eth1addr environment
variable")

when Ethernet is required in Linux, but not U-Boot.

net: Only access network devices after init

2018-03-22T20:05:31+00:00

In the efi_loader main loop we call eth_rx() occasionally. This rx function
might end up calling into devices that haven't been initialized yet,
potentially resulting in a lot of transfer timeouts.

Instead, let's make sure the ethernet device is actually initialized before
reading from or writing to it.

net: Fix netretry condition

2018-03-22T20:05:31+00:00

The "net_try_count" counter starts from "1".
And the "retrycnt" contains requested amount of retries.

With current logic, that means that the actual retry amount
will be one time less then what we set in "netretry" env.
For example setting "netretry" to "once" will make "retrycnt"
equal "1", so no retries will be triggered at all.

Fix the logic by changing the statement of "if" condition.

Convert CONFIG LIB_HW_RAND to Kconfig

2018-02-08T17:48:22+00:00

config_fallbacks.h had some logic to automatically select
LIB_RAND if RANDOM_UUID or CMD_UUID were set if LIB_HW_RAND wasn't
already selected.  By migrating LIB_HW_RAND to Kconfig, we can
remove this check from config_fallbacks.h and put it into Kconfig

net: dhcp: Allow "MAY_FAIL" to still try each adapter

2018-01-15T18:05:23+00:00

This change allows the "MAY_FAIL" DHCP option to still attempt to
contact a DHCP server on each adapter and only give up once each
adapter has failed once.  To get the existing behavior, set the
already-existing ethrotate=no variable.
