sysctl fails when default router device contains period

[Drago]

My default router is bond0.110

Running sudo sysctl -w net.ipv6.conf.bond0.110.accept_ra=2 fails because the path should be "...conf/bond.110/accept_ra..." but sysctl tries to access ""...conf/bond/110/accept_ra...".

    Allow default IPv6 route device names to have dots

    When dots are used with sysctl, they are reinterpreted as slashes.
    Route devices can have dots in their names, so when they are used in a
    sysctl command that also uses dots, its dot will be replaced with a
    slash, causing an error.
