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

Removed DEV_RX_OFFLOAD_CRC_STRIP offload flag.
Without any specific Rx offload flag, default behavior by PMDs is to
strip CRC.
PMDs that support keeping CRC should advertise DEV_RX_OFFLOAD_KEEP_CRC
Rx offload capability.
Applications that require keeping CRC should check PMD capability first
and if it is supported can enable this feature by setting
DEV_RX_OFFLOAD_KEEP_CRC in Rx offload flag in rte_eth_dev_configure()

Bonding driver ignores the value of RSS key (that is set in the port RSS
configuration) in bond_ethdev_configure(). So the only way to set
non-default RSS key is by using rss_hash_update(). This is not an

requested key is set to NULL.

Default Redirection Table that is set in bonding driver is distributed
evenly over all Rx queues only within every RETA group (the first RETA
entries in every group are always start with zero). But in the most
drivers, default RETA is distributed over all Rx queues without sequence
resets in the beginning of a new group, which implies more balanced
per-core load.
Change the default RETA to be evenly distributed over all Rx queues
considering the whole table.

>From the Intel Ethernet Controller X710/XXV710/XL710 Specification
Update:
Starting from NVM 5.02, if the Set Local LLDP MIB command is
received while the DCBx specific agent is stopped, the command
returns an EPERM error. If the command is received while the
LLDP agent is stopped, it sets the local MIB without exchanging
LLDP with peer, and returns SUCCESS.
This results in the harmless, but annoying, diagnostic:
default dcb config fails. err = -53, aq_err = 1.
So, if possible (older firmwares cannot safely stop LLDP), stop the
LLDP daemon when we are in software mod before we attempt to call
i40e_set_dcb_config.

There are a lot of cases where vhost-user massage handling
could fail and end up in a fully not recoverable state. For
example, allocation failures of shadow used ring and batched
copy array are not recoverable and leads to the segmentation
faults like this on the receiving/transmission path:
Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7f913fecf0 (LWP 43625)]
in copy_desc_to_mbuf () at /lib/librte_vhost/virtio_net.c:760
760 batch_copy[vq->batch_copy_nb_elems].dst =
This could be easily reproduced in case of low memory or big
number of vhost-user ports.
Fix that by propagating error to the upper layer which will
end up with disconnection in case we can not report to
the message sender when the error happens.
