The malloc_dma() function allocates memory with specified physical
alignment, and is typically (though not exclusively) used to allocate
memory for DMA.
Rename to malloc_phys() to more closely match the functionality, and
to create name space for functions that specifically allocate and map
DMA-capable buffers.

The VF might not have assigned a MAC address upon startup, and will
end up with a random MAC address during probe(). With this patch the
MAC address can be changed later on.

If the VF doesn't have a MAC address assigned we should create a
random MAC address.

On reset and close, the ICR register is read to clear any pending
interrupts, but the value is simply ignored. Avoid assigning the
value to a variable, to inhibit a warning from gcc 4.6.
Also fix a potential race condition in reset routines which clear
interrupts before disabling them.
