[PATCHv2] net: uclass: Save ethernet MAC address when generated

Dear Tom,

"saved to variables" ? Which variables? In C code?  In the
environment?

This is not clear here.

Same here: "ethaddr variable" - I guess this refers to the
environment variable?  Then we should write that.

Hmmm: "when the ethaddr variable ... is unset by generating ... and
setting the appropriate environment variable."  this is misleading,
as the "ethaddr variable" is not unset by setting the env var.

Suggestion:

	Selecting this will allow the Ethernet interface to function
	even when the ethaddr variable for that interface is unset.
	In this case, a random MAC address in the locally
	administered address space is generated. It will be saved to
	the appropriate environment variable, too.

Best regards,

Wolfgang Denk
