Hi Francois,

Thanks again for all your feedback.  I have implemented most of your 
suggestions,

I think so, but maybe you can help me check.  The LAN911x device is always 
directly connected to a simple SRAM-like host bus, and smsc911x_reg_write 
is implemented using readl.  Does this implicitly guarantee it to be 
volatile?

How do you mean? I thought an irq-enabled context meant i DO have to 
disable irqs?

I have removed these, they were only in as a quick fix because mii-tool 
here sends SIOCDEVPRIVATE instead of SIOCGMIIPHY.  I fixed my copy of 
mii-tool instead :o)
