Subject: Re: [PATCH v7] igb: Assign random MAC address instead of fail in case
 of invalid one

hi Leon,

Currently this module parameter is only used for igb.
Is the more user-friendly way not to use module parameters?
just like other network card drivers, use random MAC. 
As I submitted [patch v3] before, link: 
https://lore.kernel.org/netdev/20220530105834.97175-1-lianglixuehao@126.com/

Or, can you suggest me how to do it more reasonable?

Thanks
