Public bug reported:
As per the title; it looks (at first glance anyway, running
TestNetworkManager.test_eth_dhcp6_off integration test from nplan) like
NM does not set accept_ra to false, or provide a method for specifying
whether you want to accept IPv6 RAs on that device. When IPv6 is
disabled, we might also not want the kernel to heed RAs and create SLAAC
addresses.
NM already is able to disable accept_ra, since it does so when a device
transitions to UNAVAILABLE or DISCONNECTED in some cases (see
src/devices/nm-device.c).
