And the tentative flag never disappears? You should probably check why
that doesn't happen, as that's what netcfg is waiting for AIUI.
I just tested this configuration and as expected the tentative status
goes away after 2 seconds.
Your ip output includes 'flags 08' which corresponds to IFA_F_DADFAILED
(duplicate address detection failed). Which means either someone else
is already using the address you selected, or else a switch is
reflecting the packets sent during DAD.
