Change the threshold number of descriptors used to trigger CMB writes.

Fixed rare issue that 'lv1_net_start_rx_dma failed, status=-9" was shown
in dmesg.  This meant restarting rx DMA had been rejected by the hypervisor.
This issue would caused if the guest os requested starting DMA when
the hypervisor thought the DMA was in progress.
The state machine for DMA status of the hypervisor would be updated
by processing interrupt in the hypervisor.
Thus we should wait for the interrupt delivery before restarting
DMA.

gelic: TX descriptor handling cleanup

        - Emitted return value of NETDEV_TX_LOCKED when DMA map or kick
          failure.
          Now it would free the skb, update drop packet statistics
          and return OK. Requested from Jeff Garzik.
        - Enable tx queue if number of free descriptors are more than 2
        - Fixed descriptor leak if dma map for second descriptor failed
        - Stopped calling xmit handler from interrupt handler in order
          to recheck tx queue.  Instead, call appropriate helper functions.

The recent 9p commit: bd238fb4 that
supposedly only moved files also introduced a new 9p sysctl interface
that did not properly register it's sysctl binary numbers.

And since it was only for debugging clearly did not need a binary fast
path in any case.  So this patch just remove the binary numbers.

See Documentation/sysctl/ctl_unnumbered.txt for more details.

While I was at it I cleaned up the sysctl initializers a little as
well so there is less to read.
