Macvtap should be at least compatible with tap, so change the max number to 16.

- Fix the commit log of patch 7/8 ( v1 says the linked list were used which is
wrong )
- Other minor bug fixes
Jason Wang (8):
macvtap: fix a possible race between queue selection and changing
queues
macvtap: do not add self to waitqueue if doi
There's no need to add self to waitqueue if doing a nonblock read. This could
help to avoid the spinlock contention.

Even if guest were compiled without SMP support, it could not assume that host
wasn't. So switch to use mb() instead of smp_mb() to force memory barriers for
UP guest.

Currently, we use kcalloc to allocate rx/tx queues for a net device which could
be easily lead to a high order memory allocation request when initializing a
multiqueue net device. We can simply avoid this by switching to use flex array
which always allocate at order zero.

Since we've reduce the size of tun_struct and use flex array to allocate netdev
queues, it's safe for us to increase the limit of queues in tuntap.
