Subject[PATCH 4.4 25/99] skge: fix checksum byte order
Date
From: Stephen Hemminger <stephen@networkplumber.org>

[ Upstream commit 5aafeb74b5bb65b34cc87c7623f9fa163a34fa3b ]

Running old skge driver on PowerPC causes checksum errors
because hardware reported 1's complement checksum is in little-endian
byte order.
