While that may indeed be what the standard says, drv_reset_tsf() may be
needed to allow the driver to actually learn the new timestamp correctly
in the case of merge. Have you verified that the drivers that support
IBSS do indeed update their timestamps without that call in case there
is a large difference in the timestamp values that the separate IBSSes
used before the merge?
