Subject: ipv6: rearm router solicitaion timer when setting new tokenized address
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=77ecaace6c5487eae8ede633ad51478511a8e125;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ipv6: rearm router solicitaion timer when setting new tokenized address

When a new tokenized address gets installed we send out just one
router solicition. We should send out `rtr_solicits' in case one router
advertisment got lost.

So, rearm the timer as we do in addrconf_dad_complete.
