Netlink packet alignment purpose

Mon, 03 Aug 2009 15:14:14 -0700 

Hello
Can you explain me the purpose of using alignments in packets (i.e. Netlink packets)? 

I mean these macros

#define NLMSG_ALIGNTO   4
#define NLMSG_ALIGN(len) (((len)+NLMSG_ALIGNTO-1) & ~(NLMSG_ALIGNTO-1) )

and others from linux/netlink.h
They are used for separating headers from payload etc. but why?

Thanks
