1) Add a new function "rss_hash_update" in the PMD API to dynamically

hash of input packets.
The new function uses the existing data structure "rte_eth_rss_conf" for

use.
2) Add the ixgbe-specific function "ixgbe_dev_rss_hash_update" and the
igb-specific function "eth_igb_rss_hash_update" to update the RSS
hash configuration of ixgbe and igb controllers respectively.
Before changing anything, these 2 functions check that the update RSS
operation does not attempt to disable RSS, if RSS was enabled at port
initialization time, or does not attempt to enable RSS, if RSS was
disabled at port initialization time.
Note:
Configuring the RSS hash flags and the RSS key used by a NIC consists in
updating appropriate PCI registers of the NIC.
These operations have been manually tested with the interactive commands
"write reg" and "write regbit" of the testpmd application.

Each entry of the RSS redirection table (RETA) of igb and ixgbe ports
contains a 4-bit RX queue index, thus imposing RSS RX queue indices to
be strictly lower than 16.
In addition, if a RETA entry is configured with a RX queue index that is
strictly lower than 16, but is greater or equal to the number of RX queues
of the port, then all input packets whose RSS hash value indexes that RETA
entry are silently dropped by the NIC.
Make the function rte_eth_dev_rss_reta_update() check that RX queue indices
that are supplied in the reta_conf argument are strictly lower than
ETH_RSS_RETA_MAX_QUEUE (16) and are strictly lower than the number of
RX queues of the port.

82599 has two loopback operation modes, Tx->Rx and Rx->Tx.
For the time being only Tx->Rx is supported.
The new field lpbk_mode added in struct rte_eth_conf defines loopback
operation mode for certain ethernet controller. By default the value
of lpbk_mode is 0, meaning loopback mode disabled.
Since each ethernet controller has its own definition of loopback modes,
API user has to check both datasheet and implementation of certain driver
so as to understand what are valid values to be set, and what are the
expected behaviors.
Check IXGBE_LPBK_82599_XXX which are defined in ixgbe_ethdev.h

Poll Mode Driver for Paravirtual VMXNET3 NIC.
As a PMD, the VMXNET3 driver provides the packet reception and transmission
callbacks, vmxnet3_recv_pkts and vmxnet3_xmit_pkts. It does not support
scattered packet reception as part of vmxnet3_recv_pkts and
vmxnet3_xmit_pkts. Also, it does not support scattered packet reception as part of
the device operations supported.
The VMXNET3 PMD handles all the packet buffer memory allocation and resides in
guest address space and it is solely responsible to free that memory when not needed.
The packet buffers and features to be supported are made available to hypervisor via
VMXNET3 PCI configuration space BARs. During RX/TX, the packet buffers are
exchanged by their GPAs, and the hypervisor loads the buffers with packets in the RX
case and sends packets to vSwitch in the TX case.
The VMXNET3 PMD is compiled with vmxnet3 device headers. The interface is similar
to that of the other PMDs available in the Intel(R) DPDK API. The driver pre-allocates the
packet buffers and loads the command ring descriptors in advance. The hypervisor fills
those packet buffers on packet arrival and write completion ring descriptors, which are
eventually pulled by the PMD. After reception, the Intel(R) DPDK application frees the
descriptors and loads new packet buffers for the coming packets. The interrupts are
disabled and there is no notification required. This keeps performance up on the RX
side, even though the device provides a notification feature.
In the transmit routine, the Intel(R) DPDK application fills packet buffer pointers in the
descriptors of the command ring and notifies the hypervisor. In response the hypervisor
takes packets and passes them to the vSwitch. It writes into the completion descriptors
ring. The rings are read by the PMD in the next transmit routine call and the buffers
and descriptors are freed from memory.
