When setting the SO_MARK socket option, if the mark changes, the dst needs to be reset so that a new route lookup is performed.
This fixes the case where an application wants to change routing by setting a new sk_mark. If this is done after some packets have already been sent, the dst is cached and has no effect.

This patch breaks a bunch of runtime tests in the Android ecosystem, that somehow all successfully run just fine with kernels newer than 5.0 where this patch showed up in, so I think this is an "incomplete backport".
Because of this, I'm going to drop this from the stable trees now.
thanks,
