defaultenv-2: trigger DHCP before booting 'net'
Some variables may be set from DHCP requests, as shown below:
barebox@ZII VF610 Development Board, Rev C:/ echo $global.hostname
dev-rev-c
barebox@ZII VF610 Development Board, Rev C:/ echo $global.net.server
0.0.0.0
barebox@ZII VF610 Development Board, Rev C:/ dhcp
eth0: 100Mbps full duplex link detected
T T T eth0: DHCP client bound to address 192.168.203.31
barebox@ZII VF610 Development Board, Rev C:/ echo $global.hostname
zii-dev-rev-c-1
barebox@ZII VF610 Development Board, Rev C:/ echo $global.net.server
192.168.203.1
barebox@ZII VF610 Development Board, Rev C:/
These variables are used by the boot/net script, so it is necessary
to trigger DHCP before we set the TFTP file paths, otherwise booting
from net will fail like below and will need to be triggered twice:
running /env/bin/init...
Hit m for menu or any key to stop autoboot: 1

To fix this, bring the interfaces up before setting up tftpboot.
