Flow control was not documented as a supported feature
since the first fill of features matrix for mlx drivers.
Flow API and CRC offload flag support in mlx4 were missing in the
feature matrix when they were implemented (see below commits).

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.

Patch [1] zeroes the mbuf headroom when the port is configured with LRO
because when working with more than one stride per packet the HW cannot
guaranty an headroom in the start stride of each packet.
Change the solution to support mbuf headroom by adding an empty buffer
as the first packet segment, scatter mode must be enabled to support it.

LRO packet may consume all the stride memory, hence the PMD cannot
guaranty head-room for the LRO mbuf.
The issue is lack in HW support to write the packet in offset from the
stride start.
A new striding RQ feature may be added in CX6 DX to allow head-room and
tail-room for the LRO strides.

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.

This patch removes the existing Tx datapath code
as preparation step before introducing the new
implementation. The following entities are being
removed:
- deprecated devargs support
- tx_burst() routines
- related PRM definitions
- SQ configuration code
- Tx routine selection code
- incompatible Tx completion code
The following devargs are deprecated and ignored:
- "txq_inline" is going to be converted to "txq_inline_max"
for compatibility issue
- "tx_vec_en"
- "txqs_max_vec"
- "txq_mpw_hdr_dseg_en"
- "txq_max_inline_len" is going to be converted
to "txq_inline_mpw" for compatibility issue
The deprecated devarg keys are recognized by PMD
and ignored/converted to the new ones in order not
to block device probing.

Previously in the PCAP PMD queues has to be defined as RxQ and TxQ
pairs, even if the need is only Rx or only Tx:
"--vdev net_pcap0,tx_pcap=tx.pcap,rx_pcap=rx.pcap"
Following commit enabled only providing Rx queue, and if Tx queue is
not provided PMD drops the Tx packets automatically:
Commit a3f5252e5cbd ("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")

Enabled IP-in-IP tunnel type support on DV/DR flow engine.
This includes the following combination:
- IPv4 over IPv4
- IPv4 over IPv6
- IPv6 over IPv4
- IPv6 over IPv6
MLX5 NIC supports IP-in-IP tunnel via FLEX Parser so
need to make sure fw using FLEX Paser profile 0.
mlxconfig -d <mst device> -y set FLEX_PARSER_PROFILE_ENABLE=0
The example testpmd commands would be:
- Match on IPv4 over IPv4 packets and do inner RSS:
testpmd> flow create 0 ingress pattern eth / ipv4 proto is 0x04 /
ipv4 / udp / end actions rss level 2 queues 0 1 2 3 end / end
- Match on IPv6 over IPv4 packets and do inner RSS:
