      sis900: Allocate rx replacement buffer before rx operation · dc5a1449
      Neil Horman authored
      Just found a hole in my last patch.  It was reported to me that shortly after we
      integrated this patch.  The report was of an oops that took place inside of
      netif_rx when using the sis900 driver.  Looking at my origional patch I noted
      that there was a spot between the new skb_alloc and the refill_rx_ring label
      where skb got reassigned to the pointer currently held in the rx_ring for the
      purposes of receiveing the frame.  The result of this is however that the buffer
      that gets passed to netif_rx (if it is called), then gets placed right back into
      the rx_ring.  So if you receive frames fast enough the skb being processed by
      the network stack can get corrupted.  The reporter is testing out the fix I've
      written for this below (I'm not near my hardware at the moment to test myself),
      but I wanted to post it for review ASAP.  I'll post test results when I hear
      them, but I think this is a pretty straightforward fix.  It just uses a separate
      pointer to do the rx operation, so that we don't improperly reassign the pointer
      that we use to refill the rx ring.

      Simplify pegasus carrier detection; rely only on the periodic MII
      polling.  Reverts pieces of c43c49bd.
