387bf3006c fm10k: add Rx/Tx single queue start/stop
1. Add 4 functions fm10k_dev_rx_queue_start,
   fm10k_dev_rx_queue_stop, fm10k_dev_tx_queue_start,
   and fm10k_dev_tx_queue_stop.
2. verify Rx packet buffer alignment is valid.
   Hardware requires specific alignment for Rx packet buffers. At
   least one of the following two conditions must be satisfied.
       1) Address is 512B aligned
       2) Address is 8B aligned and buffer does not cross 4K boundary.

   Alignment is checked by the driver when the Rx queue is reset. It
   is assumed that if an entire descriptor ring can be filled with
   buffers containing valid alignment, then all buffers in that mempool
   have valid address alignment. It is the responsibility of the user
   to ensure all buffers have valid alignment, as it is the user who
   creates the mempool.

   It is assumed the buffer needs only to store a maximum size Ethernet
   frame.

0c0c43705c i40e: fix offloading of outer checksum for IPIP tunnel
When offloading the checksums of ipip tunnels, m->l2_len is set to 0
as there is no tunnel or inner l2 header. Since this is a valid value
remove the test.

By the way, also remove the same test with l3_len because at this
point, it is expected that the software provides proper values in the
mbuf. It should avoid a test in dataplane processing and therefore
slightly increase performance.

59cfa76a22 i40e: remove the use of UDP tunnel flag
The definition of the flag PKT_TX_UDP_TUNNEL_PKT in rte_mbuf.h was:
  TX packet is an UDP tunneled packet. It must be specified when using
  outer checksum offload (PKT_TX_OUTER_IP_CKSUM)

This flag was used to tell the NIC that the offload type is UDP
(I40E_TXD_CTX_UDP_TUNNELING flag). In the datasheet, it says it's
required to specify the tunnel type in the register. However, some tests
(see [1]) showed that it also works without this flag.

Moreover, it is not explained how the hardware use this
information. From a network perspective, this information is useless for
calculating the outer IP checksum as it does not depend on the payload.

Having this flag in the API would force the application to specify the
tunnel type for something that looks only useful for this PMD. It will
limit the number of possible tunnel types (we would need a flag for each
tunnel type) and therefore prevent to support outer IP checksum for
proprietary tunnels.

Finally, if a hardware advertises "I support outer IP checksum", it must
be supported for any payload types.

This has been validated by [2], knowing that the ipip test case was fixed
after this test report [3].

e3f0151fc6 i40e: enable Tx checksum only for offloaded packets
From i40e datasheet:

  The IP header type and its offload. In case of tunneling, the IIPT
  relates to the inner IP header. See also EIPT field for the outer
  (External) IP header offload.

  00 - non IP packet or packet type is not defined by software
  01 - IPv6 packet
  10 - IPv4 packet with no IP checksum offload
  11 - IPv4 packet with IP checksum offload

Therefore it is not needed to fill the IIPT field if no offload is
requested (we can keep the value to 00). For instance, the linux driver
code does not set it when (skb->ip_summed != CHECKSUM_PARTIAL). We can
do the same in the dpdk driver.

The function i40e_txd_enable_checksum() that fills the offload registers
can only be called for packets requiring an offload.

ecd9d5193b bond: remove offload flags from transmit policy checks
The Link bonding library is incorrectly using receive packet type flags
in the transmit policy hashing functions, which would cause packets
generated locally to be incorrectly distributed across the slave
devices. This patch completely removes the dependency on the packet
type flags and uses the ether_type from either the Ethernet header or
the VLAN headers for branching.

This patch also includes the associate changes in the test suite and in
the packet_burst_generator code to remove the dependences on the packet
type flags.

62945e029e acl: introduce config parameter for performance/space trade-off
If at build phase we don't make any trie splitting,
then temporary build structures and resulting RT structure might be
much bigger than current.
>From other side - having just one trie instead of multiple can speedup
search quite significantly.
>From my measurements on rule-sets with ~10K rules:
RT table up to 8 times bigger, classify() up to 80% faster
than current implementation.
To make it possible for the user to decide about performance/space trade-off -
new parameter for build config structure (max_size) is introduced.
Setting it to the value greater than zero, instructs  rte_acl_build() to:
- make sure that size of RT table wouldn't exceed given value.
- attempt to minimise number of tries in the table.
Setting it to zero maintains current behaviour.
That introduces a minor change in the public API, but I think the possible
performance gain is too big to ignore it.

bfca21f8a0 ixgbe: add queue start failure check
For ixgbe, when queue start fails, for example, mbuf allocate
