This patch adds support for MAC PAUSE flow control and priority flow
control(PFC).
MAC PAUSE flow control features:
All user priorities(up) are mapped to tc0. It supports settings of flow
mode and pause time.
DCB features:
Up can be mapped to other tc driver permits according to business
requirement. We can config DCB information and enable PFC by
rte_eth_dev_configure interface. Besides, enabling flow control of a
priority is supported by rte_eth_dev_priority_flow_ctrl_set interface.
we can also set flow mode and pause time by
rte_eth_dev_priority_flow_ctrl_set. we do not support manual setting of
ETS, but driver equally distributes bandwidth for each tc according to
number of used tc.
In addition, flow control function by default is turned off to ensure
that app startup state is the same each time.

This patch adds the feature that supports loading DDP package
according to the device serial number. Prior to loading the
default DDP package (ice.pkg), the driver will check for the
presence of a device-specific DDP package with the name containing
64-bit PCIe Device Serial Number (ice-xxxxxxxxxxxxxxxx.pkg)
during initialization. Users can use "lspci -vs" to get the device
serial number.
The pkg search path are /lib/firmware/updates/intel/ice/ddp/
and /lib/firmware/intel/ice/ddp/. If the package exists,
the driver will download it to the device instead of the default
one. The loaded package type (OS default and COMMS) will be
stored in ice_adapter->active_pkg_type. The package version is
stored in ice_hw->active_pkg_ver.

When LRO offload is configured in Rx queue, the HW may coalesce TCP
packets from same TCP connection into single packet.
In this case the SW should fix the relevant packet headers because
the HW doesn't update them according to the new created packet
characteristics but provides the update values in the CQE.
Add update header code to the regular Rx burst function to support LRO
feature.
Make sure the first mbuf has enough space to include each TCP header,
otherwise the header update may cross mbufs what complicates the
operation too match.

This patch introduces new mlx5 PMD devarg options:
- txq_inline_min - specifies minimal amount of data to be inlined into
WQE during Tx operations. NICs may require this minimal data amount
to operate correctly. The exact value may depend on NIC operation
mode, requested offloads, etc.
- txq_inline_max - specifies the maximal packet length to be completely
inlined into WQE Ethernet Segment for ordinary SEND method. If packet
is larger the specified value, the packet data won't be copied by the
driver at all, data buffer is addressed with a pointer. If packet
length is less or equal all packet data will be copied into WQE.
- txq_inline_mpw - specifies the maximal packet length to be completely
inlined into WQE for Enhanced MPW method.
Driver documentation is also updated.

- "txq_mpw_hdr_dseg_en"

Previously in the PCAP PMD queues has to be defined as RxQ and TxQ

Following commit enabled only providing Rx queue, and if Tx queue is
not provided PMD drops the Tx packets automatically:
Commit a3f5252e5c ("net/pcap: enable infinitely Rx a pcap file")
"--vdev net_pcap0,rx_pcap=rx.pcap"
This commit enables same thing for Rx queue, user no more have to
provide a Rx queue (rx_iface or rx_pcap), for this case a dummy Rx
burst function is used which doesn't return any packet at all:
"--vdev net_pcap0,tx_pcap=tx.pcap"
This makes only saving packets to a pcap file use case easy.
When both Rx and Tx queues are missing PMD will return an error.
(Single interface is still supported: "--vdev net_pcap0,iface=eth0")
