>Description:
IN6_IS_ADDR_V4MAPPED does some casts, but omits "const" from the cast, thus,

	if (IN6_IS_ADDR_V4MAPPED(
	    &((const struct sockaddr_in6 *)sa)->sin6_addr)) {

will cause bogus compiler warnings.

	
>How-To-Repeat:
	
>Fix:
	Fix the IN6_IS_ADDR_* macros to cast to const if they intend to only read.
