Subject: drivers/net/sunhme.c patch

This patch provides a unique mac address for all interfaces
for the Sun QFE card (non-sparc).  It takes the base mac from
the first interface and increments the mac address for the
other interfaces.

It still preserves the 'macaddr' parameter so if desired, it
can still be used.

Before patching:

eth0      Link encap:Ethernet  HWaddr 00:03:BA:17:4C:BB
eth1      Link encap:Ethernet  HWaddr 00:03:BA:17:4C:BB
eth2      Link encap:Ethernet  HWaddr 00:03:BA:17:4C:BB
eth3      Link encap:Ethernet  HWaddr 00:03:BA:17:4C:BB

After patching:

eth0      Link encap:Ethernet  HWaddr 00:03:BA:17:4C:BB
eth1      Link encap:Ethernet  HWaddr 00:03:BA:17:4C:BC
eth2      Link encap:Ethernet  HWaddr 00:03:BA:17:4C:BD
eth3      Link encap:Ethernet  HWaddr 00:03:BA:17:4C:BE

Cheers,

Tom
