e1000: Fix multi-descriptor packet checksum offload
The PCI/PCI-X Family of Gigabit Ethernet Controllers Software Developer’s Manual states the following about the POPTS field: Provides a number of options which control the handling of this packet. This field is ignored except on the first data descriptor of a packet. The current implementation always loads the field and its checksum offload flags. This patch uses only the first descriptor's POPTS field in order to comply with the specification. When Solaris sends multi-descriptor packets it fills in POPTS for the first descriptor only. Therefore this patch is necessary in order to perform checksum offload correctly for multi-descriptor packets. Reported-by: Daniel Pecka <dpecka@techniservit.cz> Reported-by: Gabriele A.
