 lldp
 sleep 2s
 lldp

With the first "lldp" invocation the network is activated and then I
need to sleep a bit (I don't know if 1s or less is working but with
no wait it certainly doesn't work).

With checking the phy you refer to the call of eth_carrier_check that
is used by eth_send?

kind regards
