[ Upstream commit b9389796fa4c87fbdff33816e317cdae5f36dd0b ]

sky2 driver on PowerPC targets floods kernel log with following errors:

  eth1: hw csum failure.
  Call Trace:
  [ef84b8a0] [c00075e4] show_stack+0x50/0x160 (unreliable)

  [ef84ba20] [c02fb7fc] net_rx_action+0xc0/0x144

The NIC is Yukon-2 EC chip revision 1.

Converting checksum field from le16 to CPU byte order fixes the issue.
