hardware.

[U-Boot] [PATCH 3/3] smc911x: do net reset the chip if no EEPROM is connected

[Daniel Mack]

On boards without EEPROMs, don't reset the chip on U-Boot's exit so that
the MAC set by environment settings can be used by the OS later.

that isnt how the MAC is passed to the OS ... this change is incorrect

the OS must be able to get the MAC address regardless of the state of the 
network controller

Not if the MAC is stored in the volatile smc911x registers. Issuing a
soft reset flushes these values - if U-Boot does that, the OS has no
change getting them.

That's what I saw here and it is also stated in the datasheet.

then either your u-boot or your OS is misconfigured and you need to fix that.  
as clearly stated in docs/README.enetaddr, the environment is the place where 
mac addresses live when there is no dedicated storage (like an eeprom).

ignoring that, the mac address doesnt magically get programmed.  if no network 
operation was initiated, then the part wouldnt have been programmed anyways, 
so you're still left with an OS that cant get itself functional.

sounds like the driver and hardware is operating correctly then

usually what i suggest to people are things like:
 - pass $(ethaddr) via kernel command line and parse /proc/cmdline
 - use the u-boot tools to read the u-boot env directly
 - set the hw address with `ifconfig` or similar tool

... which doesn't help much when it's about booting from NFS root. The
particular problem here is that the MAC changes from what it's set to in
U-Boot during the TFTP transaction and the randomly chosen one in Linux
(which takes place because after the reset, the MAC is all 0xff). And
that in turn confuses the ARP caches on other hosts. My patch solves
that issue for that very case; that's why it's still in my local tree.

it works fine if you use an initramfs like everyone suggests

Anyway, you shouldn't rely on this. I'm the original author of this
driver, but I do not use U-Boot-v1 anymore, so I can't tell if this
breaks something or not.

No problem. I just Cc'ed all email addresses I could find in the code.

Who will pick that one and the one regarding support for the 9220
controller for mainline?

Network drivers are my responsibility.  Please CC me in the future as it
stands out more clearly.  I guess I was waiting on you to resolve 3/3, but
instead can pick up parts 1 and 2 if you like.

I'll try to solve 3/3 in another fashion, so feel free to merge the
other two.
