df694a05bf ethdev: add Tx offload outer UDP checksum definition
Introduced DEV_TX_OFFLOAD_OUTER_UDP_CKSUM offload flags and
PKT_TX_OUTER_UDP_CKSUM mbuf ol_flags to enable Tx outer UDP
checksum offload.

To use hardware Tx outer UDP checksum offload, the user needs to,

- enable following in mbuf:
a) fill outer_l2_len and outer_l3_len in mbuf
b) set the PKT_TX_OUTER_UDP_CKSUM flag
c) set the flag PKT_TX_OUTER_IPV4 or PKT_TX_OUTER_IPV6

- configure DEV_TX_OFFLOAD_OUTER_UDP_CKSUM offload flags in slow path

6bc985e411 net/sfc: support TSO in EF10 Tx datapath
Implementation includes following limitations:

1) Packet's header length must be less than 256 (SFC_TSOH_STD_LEN);
2) Offset of the TCP header must be less than 208
   (EF10_TCP_HEADER_OFFSET_LIMIT);
3) Number of Tx descriptors must be not less than number of descriptors
   needed for TSO settings plus header plus one data segment.

If above conditions are not met, the packet is dropped.

If the maximum descriptor space is insufficient to hold entire TSO packet,
only a part of the packet is sent.

8a6ff33d6d net/enic: add AVX2 based vectorized Rx handler
Add the vectorized version of the no-scatter Rx handler. It aims to
process 8 descriptors per loop using AVX2 SIMD instructions. This
handler is in its own file enic_rxtx_vec_avx2.c, and makefile and
meson.build are modified to compile it when the compiler supports
AVX2. Under ideal conditions, the vectorized handler reduces
cycles/packet by more than 30%, when compared against the no-scatter
Rx handler. Most implementation ideas come from i40e's AVX2 based
handler, so credit goes to its authors.

At this point, the new handler is meant for field trials, and is not
selected by default. So add a new devarg enable-avx2-rx to allow the
user to request the use of the new handler. When enable-avx2-rx=1, the
driver will consider using the new handler.

Also update the guide doc and introduce the vectorized handler.

e04ec42af0 net/mvpp2: align with MUSDK 18.09
This patch introduces necessary changes required by MUSDK 18.09 library.

* As of MUSDK 18.09, pp2_cookie_t is no longer available. Now
  RX descriptor cookie is defined as plain u64 so existing cast
  is no longer valid.

* MUSDK 18.09 increased number of available bpools (buffer hw pools) by
  introducing dma regions support. Update mvpp2 driver accordingly.

* replace MV_NET_IP4_F_TOS with MV_NET_IP4_F_DSCP

  Before this patch, API allowed to configure a classification rule
  according to IPv4 TOS, which was not supported in classifier. This patch
  fixes this by using proper field.

* use 48 bit address mask

  We cannot get pointers exceeding 48 bits thus using 48 bit
  mask for extracting higher IOVA address bits is enough.

c11f654042 net/i40e: add option to use latest vector path
For IA, the AVX2 vector path is only recommended to be used on later
platforms (identified by AVX512 support, like SKL etc.) This is because
performance benchmark shows downgrade when running AVX2 vector path on
early platform (BDW/HSW) in some cases. But we still observe perf gain
with some real work loading.

So this patch introduced the new devarg use-latest-supported-vec to
force the driver always selecting the latest supported vec path. Then
apps are able to take AVX2 path on early platforms. And this logic can
be re-used if we will have AVX512 vec path in future.

This patch only affects IA platforms. The selected vec path would be
like the following:
  Without devarg/devarg = 0:
  Machine	vPMD
  AVX512F	AVX2
  AVX2	SSE4.2
  SSE4.2	SSE4.2
  <SSE4.2	Not Supported

  With devarg = 1
  Machine	vPMD
  AVX512F	AVX2
  AVX2	AVX2
  SSE4.2	SSE4.2
  <SSE4.2	Not Supported

Other platforms can also apply the same logic if necessary in future.

dc7680e859 net/netvsc: support integrated VF
Integrate accelerated networking support into netvsc PMD.
This allows netvsc to manage VF without using failsafe or vdev_netvsc.
For the exception vswitch path some tests like transmit
get a 22% increase in packets/sec.
For the VF path, the code is slightly shorter but has no
real change in performance.

Pro:
   * using netvsc is more like other DPDK NIC's
   * the exception packet uses less CPU
   * much smaller code size
   * no locking required on VF transmit/receive path
   * no legacy Linux network device to get mangled by userspace
   * much simpler (1K vs 9K) LOC
   * unified extended statistics

Con:
   * using netvsc has more complex startup model
   * no bifurcated driver support
   * no flow support (since host does not have flow API).
   * no tunnel offload support
   * no receive interrupt support
