the old commit changed the linux_sendto() to ignore the target address if the socket state is in a connected/connecting state.
This commit causes many issues now, such as ARP packet sending failure, wpa_supplier failed to send L2 packets.

Can you please name the old commit and provide a test scenario that it broke? It is hard to understand what is the problem we are trying to fix here.

this is the old commit:

Hi glebius,
I made a mistake. There was a bug with the code we added ourselves. After I fixed it, the issue cannot reproduce now.
FreeBSD codes are no problem, because every time before in6_purgeaddr is called, the CK_STAILQ_FOREACH_SAFE has run.
I'm abandoning it now.

update code comment

update the code comment.

change the parameter of nd6_dad_timer to ifa, then before run, find dp by ifa.

@zlei
There are two same default route tables in my system , and both default route tables only have "Flags" difference(one is UG, another is UGS).
The kernel self cannot guarantee that routes will not be added repeatedly, maybe dhcp client or other user application add the same route entry.

D41842 is accepted, so abandon it.
