====================
FUJITSU Extended Socket network device driver

This patchsets adds FUJITSU Extended Socket network device driver.
Extended Socket network device is a shared memory based high-speed
network interface between Extended Partitions of PRIMEQUEST 2000 E2
series.

You can get some information about Extended Partition and Extended
Socket by referring the following manual.

http://globalsp.ts.fujitsu.com/dmsp/Publications/public/CA92344-0537.pdf
    3.2.1 Extended Partitioning
    3.2.2 Extended Socke

v2.2 -> v3:
   - Fix up according to David's comment (No functional change)
