modinfo network controller

How can I interpret the output of the "modinfo" command.
For example, the network module information is

Code:

depends:        mii

parm:           debug:Debug verbosity level (0=none, ..., 16=all) (int)

On another linux (which has intel controller), I see that the depends" field is empty. So what does "mii" mean here?

Also, how can I enable the debug verbosity? it says there are 16 levels!

Another module. Run 'modinfo mii'.

If you want it permanently add an entry 'echo "options r8169 debug=16" >> /etc/modprobe.conf' or use an /etc/modprobe.d/ entry elif it's a one-off then 'modprobe r8169 debug=16' should set it but you may have to 'rmmod r8169' before that which your system probably won't allow if the card is in use.
