The add_ra_header function had a hidden dependency on system state: If cease_adv was not set, the outcome was dependent on the sysctl knob "net.ipv6.conf.all.forwarding". This was visible only during testing with net.ipv6.conf.all.forwarding=1. If tested with net.ipv6.conf.all.forwarding=0, the tests passed. Hoist the sysctl dependency out of the add_ra_header function, to enable testing of both code paths, and add the extra test to validate both states of the cease_adv input.
