2018-02-08Convert CONFIG LIB_HW_RAND to KconfigAdam Ford
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 Signed-off-by: Adam Ford <aford173@gmail.com> Reviewed-by: Lukasz Majewski <lukma@denx.de> [trini: Turn into a choice, add NET_RANDOM_ETHADDR] Signed-off-by: Tom Rini <trini@konsulko.com>
2018-01-15net: dhcp: Allow "MAY_FAIL" to still try each adapterJoe Hershberger
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.
