AFAICS ixgbe_alloc_q_vector() is also called in probe() (by ixgbe_init_interrupt_scheme()).
Furthermore it is also called in resume() which would lead to multiple initialization of
the u64_stats_sync in case of resume.
IMHO the u64_stats_sync variables have to be initialized before register_netdev() is called
since this is the point from which userspace can call ixgbe_get_stats64(). I would say the
best place to do so is the probe() function as it is done in this patch.
Just my 2 cents.

Lino
