Currently, libnl and libnetfilter_queue include in one of their
user-space header files an ad-hoc definition of aligned_be64.
However, applications that use the BSD socket API to communicate
via Netlink sockets (ie. those that do not use these libraries)
would need to define this type by hand if they include the
kernel-space header nfnetlink_queue.h.
This patch adds the definition of aligned_bed64 for user-space
applications in the kernel header. Otherwise, they have to define
it to avoid the following compilation problem:
/usr/include/linux/netfilter/nfnetlink_queue.h:28: error: expected specifier-qualifier-list before ‘aligned_be64’
I know, this is ugly but I think that user-space Netlink applications
should compile with the only need of including the kernel-space
header that contains the protocol definitions.
