[netdrvr 3c527] remove cli/sti

    Richard Procter and I worked to remove cli/sti to add proper SMP support (I did the original stuff and Richard did the actual current code :)).

    Besides that, Richard did a great jog improving the perfomance of the driver quite a bit:

    - Improve mc32_command by 770% (438% non-inlined) over the semaphore version (at a cost of 1 sem + 2 completions per driver).

    - Removed mutex covering mc32_send_packet (hard_start_xmit). This lets the interrupt handler operate concurrently and removes unnecessary locking. It makes the code only slightly more brittle

    Since it didn't apply cleanly against 2.6.0-test6, I forward ported it. Patch attached.

    Jeff, please consider applying,

    Thanks.
