sky2: disable rx checksum on Yukon XL
The Marvell Yukon XL chipset appears to have a hardware glitch
where it will repeat the checksum of the last packet. Of course, this is
timing sensitive and only happens sometimes...
More info: http://bugzilla.kernel.org/show_bug.cgi?id=9381
As a workaround just disable hardware checksumming by default on
this chip version. The earlier workaround for PCIX, dual port
was also on Yukon XL so don't need to disable checksumming there.
