Interesting the way that Davicom handle changes to CSR6.  All changes
are done via

/*
  Update CR6 vaule
  Firstly stop DM910X , then written value and start
*/
static void update_cr6(u32 cr6_data, u32 ioaddr)
 {
  u32 cr6_tmp;
  
  cr6_tmp=cr6_data & ~0x2002;           /* stop Tx/Rx */
  outl(cr6_tmp, ioaddr+DCR6);
  DELAY_5US;
  outl(cr6_data, ioaddr+DCR6);
  cr6_tmp=inl(ioaddr+DCR6);
  /* printk("CR6 update %x ", cr6_tmp); */
 }

Rather like the kludge I had to put into the Xircom Cardbus driver.
Without some delay, the MAC setup frame was being lost.
