[ovs-dev] [PATCH] windows/netinet: Import ip6.h and icmp6.h from netbsd.

Gurucharan Shetty shettyg at nicira.com
Wed Mar 12 18:21:19 UTC 2014


There are a few structure definitions that is used from
these headers. The keyword "__packed" has been removed
from the headers as the corresponding Linux headers don't
do packing.
