+
+ 8139cp: set ring address after enabling C+ mode
+
+ This fixes (for me) a regression introduced by commit b01af457 ("8139cp:
+ set ring address before enabling receiver"). That commit configured the
+ descriptor ring addresses earlier in the initialisation sequence, in
+ order to avoid the possibility of triggering stray DMA before the
+ correct address had been set up.
+
+ Unfortunately, it seems that the hardware will scribble garbage into the
+ TxRingAddr registers when we enable "plus mode" Tx in the CpCmd
+ register. Observed on a Traverse Geos router board.
+
+ To deal with this, while not reintroducing the problem which led to the
+ original commit, we augment cp_start_hw() to write to the CpCmd register
+ *first*, then set the descriptor ring addresses, and then finally to
+ enable Rx and Tx in the original 8139 Cmd register. The datasheet
+ actually indicates that we should enable Tx/Rx in the Cmd register
+ *before* configuring the descriptor addresses, but that would appear to
+ re-introduce the problem that the offending commit b01af457 was trying
+ to solve. And this variant appears to work fine on real hardware.
