Looks nice and clean to me.  Pre-merge stuff I think needs fixing:

* clean up NAPI as you describe (and delete non-NAPI code paths, unless 
there is a strong reason to keep them).

* unconditional local_irq_{enable,disable} stuff

* spin_lock_irqsave() should not be needed in interrupt handler. 
[perhaps you did this rather than put the slower locking in 
->poll_controller()]

* remove changelog from C header (git repository log is our changelog)

* handle large dev->mc_count, as you note in the C header

* use __le32 and similar data types. validate with sparse 
(Documentation/sparse.txt)

* consider using ioread{8,16,32} and iowrite{8,16,32}, if your platform 
permits.  Then switch from 'unsigned long' to special marker 'void 
__iomem *' for all I/O port addresses

* use DMA_32BIT_MASK rather than 0xffffffff in pci_set_dma_mask() call

* in r6040_init_one() call is_valid_ether_addr(), rather than 
hand-rolling the same code yourself

* you need to note carrier state when it changes, using 
netif_carrier_on() and netif_carrier_off()
