1) Add a new function "rss_hash_conf_get" in the PMD API to retrieve the
current configuration of the RSS functions and/or of the RSS key used
by a NIC to compute the RSS hash of input packets.
The new function uses the existing data structure "rte_eth_rss_conf" for
returning the RSS hash configuration.
2) Add the ixgbe-specific function "ixgbe_dev_rss_hash_conf_get" and the
igb-specific function "eth_igb_rss_hash_conf_get" to retrieve the RSS
hash configuration of ixgbe and igb controllers respectively.
3) Add the command "show port X rss-hash [key]" in the testpmd application
to display the RSS hash configuration of port X.

1) Add a new function "rss_hash_update" in the PMD API to dynamically
update the RSS flags and/or the RSS key used by a NIC to compute the RSS
hash of input packets.
The new function uses the existing data structure "rte_eth_rss_conf" for
the argument that contains the new hash flags and/or the new hash key to
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.

This field is intended for pcap to describe the name of the interface
as known to Linux. It is an interface index, but can be translated into
an interface name using if_indextoname() function.
When using pcap, interrupt affinity becomes important, and this field
gives the application a chance to ensure that interrupt affinity is set
to the lcore handling the device.

1) Make device RX and TX offload capabilities to be returned in the
rte_eth_dev_info data structure by the function rte_eth_dev_info_get
The following initial set of RX offload capabilities are defined:
- VLAN header stripping
- IPv4 header checksum check
- UDP checksum check
- TCP checksum check
- TCP large receive offload (LRO)
The following initial set of TX offload capabilities are defined:
- VLAN header insertion
- IPv4 header checksum computation
- UDP checksum computation
- TCP checksum computation
- SCTP checksum computation
- TCP segmentation offload (Transmit Segmentation Offload)
- UDP segmentation offload
2) Update the eth_dev_infos_get() function of the igb and ixgbe PMDs
to return the offload capabilities which are supported by the
device and that are effectively managed by the driver.

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
for valid values of 82599 loopback mode.

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.
