Symptom:     slow CCL response time
Problem:     non-ETH_P_802_2 packets are not delivered to NDH for
             CCL. But CCL detects missing sequence numbers, which
             cause a serious performance problem with CCL.
Solution:    assign sequence numbers only to 802.2 packets.

Problem:     A STARTLAN command from the adapter may arrive while a
             qeth recovery is currently running with a failed qeth
             STARTLAN. Usually qeth schedules a recovery when
             receiving a STARTLAN command from the adapter. But
             another recovery scheduled while a recovery is already
             running never starts. Thus the qeth-administered
             lan_online flag remains zero in this scenario, even
             though the adapter-STARTLAN has happened.
Solution:    Set lan_online flag for a received STARTLAN from the
             adapter in case scheduled recovery does not start.

winbond-840 shares tulip.h with the tulip driver, because they share
many (but not all) of the same register definitions.

This is useful for the register definitions, but not helpful when it
comes to symbols that are shared among the tulip driver's C modules,
but not meant to be shared outside that one driver.

Thus, PKT_BUF_SZ is a symbol internal to tulip, but it was intruding
upon a similar symbol in winbond-840's namespace.  This was not a
problem as long as the two symbols had the same value, but upcoming
patches result in differing symbol values.

The alloc_netdev_mq() tries to produce 32-bytes alignment for both
the net_device itself and its private data. The second alignment is
achieved by adding the NETDEV_ALIGN_CONST to the whole size of
the memory to be allocated.

However, for those devices that do not need the private area, this
addition just makes the net_device weight 1024 + 32 = 1068 bytes,
i.e. consume twice as much memory.

Since loopback device is such (sizeof_priv == 0 for it), and each
net namespace creates one, this can save a noticeable amount of
memory for kernel with net namespaces turned on.

After this set the lo device is actually allocated from a size-1024
kmem cache on i386 box even with NETPOLL and WIRELESS_EXT turned on.
