Fixes an issue of check logic in delete_depth_small function.
For a tbl24 entry, the 'ext_entry' field indicates whether we need
to use tbl8_gindex to read the next_hop from a tbl8 entry, or whether
it can be read directly from this entry.
If a route is deleted, the prefix of previous route is used to override
the deleted route.
When checking the depth of the previous route the conditional checks
both the ext_entry and the depth, but the "else" leg fails to take
account that the condition could fail for one of two possible reasons,
leading to an incorrect flow when 'ext_entry == 0' is true,
but 'lpm->tbl24[i].depth > depth' is false.

virtio: optimize ring layout
In DPDK based switching environment, mostly vhost runs on a dedicated core
while virtio processing in guest VMs runs on different cores.
Take RX for example, with generic implementation, for each guest buffer,
a) virtio driver allocates a descriptor from free descriptor list
b) modify the entry of avail ring to point to allocated descriptor
c) after packet is received, free the descriptor
When vhost fetches the avail ring, it need to fetch the modified L1 cache from
virtio core, which is a heavy cost in current CPU implementation.
This idea of this optimization is:
allocate the fixed descriptor for each entry of avail ring, so avail ring will
always be the same during the run.
This removes L1M cache transfer from virtio core to vhost core for avail ring.
(Note we couldn't avoid the cache transfer for descriptors).
Besides, descriptor allocation and free operation is eliminated.
This also makes vector procesing possible to further accelerate the processing.
This is the layout for the avail ring(take 256 ring entries for example), with
each entry pointing to the descriptor with the same index.
avail
idx

|
+----+----+---+-------------+------+
| 0 | 1 | 2 | ... | 254 | 255 | avail ring

+----+----+---+-------------+------+
| 0 | 1 | 2 | | 254 | 255 | used ring
+----+----+---+-------------+------+

This is the ring layout for TX.
As we need one virtio header for each xmit packet, we have 128 slots available.

1) RSS hash function set for bonding device is maximal set of RSS hash
functions supported by all bonded devices. That mean, to have RSS support
for bonding, all slaves should be RSS-capable.
2) RSS key is propagated over the slaves "as is".
3) RETA for bonding is an internal table managed by bonding API, and is

it can be easily used as a pattern providing expected behavior, even if
