This way you can specify as previously set the dhcp parameter via global.dhcp.xxx
and get the result via global.dhcp.xxx
This is need for the defaultenv-2 to add the bootp suppport.
Use it on defaultenv too to have only one set of var.

Adapt phylib from linux
switch all the driver to it
reimplement mii bus
This will allow to have
- phy drivers
- to only connect the phy at then opening of the device
- if the phy is not ready or not up fail on open
Same behaviour as in linux and will allow to share code and simplify porting.

The dhcp command starts with an unitialized start time. The start
time is often long in the past which results in an immediate timeout
and resend of the dhcp packet. Fix this by initializing the start time

For net boot setups it is useful to submit boot params like server or
