gre/gre6: allow clearing {,i,o}{key,seq,csum} flags
Currently, iproute allows setting those flags, but it's impossible to clear them, since their current value is fetched from the kernel and then we OR in the additional flags passed on the command line. Add no* variants to allow clearing them. Signed-off-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: David Ahern <dsahern@gmail.com>
