Linux's netconsole works much better when you can pass it the MAC address of
the server. (otherwise it just uses broadcast, which everyone else on my
network complains about :)
This sets the evn var "serveraddr" (to match ethaddr), so that you can pass
it to linux with whatever bootargs you want to....
addnetconsole=set bootargs $(bootargs)
netconso...@$(ipaddr)/eth0,@$(serverip)/$(serveraddr)
I'm sure this is white space damaged - but you get the idea...
