smsc9420: fix big endian rx checksum offload
Steve Glendinning [Fri, 20 Mar 2009 08:14:53 +0000 (01:14 -0700)]
The cpu_to_le16 here looks suspicious to me, I don't think we need it
because put_unaligned_le16 also does this.

I don't currently have any big endian hardware with a PCI bus available
to test on, so I haven't been able to verify this.
