[U-Boot] [PATCH] net/eth: Don't issue warnings for offboard ethernet chips

[Wolfgang Denk <wd@denx.de>]

Dear Kyle Moffett,

Yes, it should.  The rule is that then environment settings always
have precedence, and if they are missing or contain different data
than other sources for this inofmration, a waning shall be printed.

This is also not correct.  There should never be any printing of the
MAC addresses here.

The messages should be:

	Net:   owt0, owt1, peer, e1000#0, e1000#1

No.  "could not set" is an error message, and deserves a separate
line.
