The associated device index is retrieved via Netlink request to
underlying Infiniband device driver. This network device index
is permanent throughout the lifetime of device. We do not
spawn the rte_eth_dev ports without associated network device, and
if network device is being unbound we get the remove notification
message and rte_eth_dev port is also detached. So, we may store
the ifindex in mlx5_device_spawn() routine at rte_eth_dev port
creation and initialization time and use the cached value further
instead of doing actual Netlink request.

This patch adds the implementation of tx_burst routine template.
The template supports all Tx offloads and multiple optimized
tx_burst routines can be generated by compiler from this one.

Mellanox NICs support the wide set of Tx offloads. The supported
offloads are reported by the mlx5 PMD in rte_eth_dev_info
tx_offload_capa field.
An application may choose any combination of supported offloads
and configure the device appropriately. Some of Tx offloads may be
not requested by application, or ever all of them may be omitted.
Most of the Tx offloads require some code branches in tx_burst routine
to support ones. If Tx offload is not requested the tx_burst routine
code may be significantly simplified and consume less CPU cycles.
For example, if application does not engage TSO offload this code
can be omitted, if multi-segment packet is not supposed the tx_burst
may assume single mbuf packets only, etc.
Currently, the mlx5 PMD implements multiple tx_burst subroutines
for most common combinations of requested Tx offloads, each branch
has its own dedicated implementation. It is not very easy to update,
support and develop such kind of code - multiple branches impose
the multiple points to process. Also many of frequently requested
offload combinations are not supported yet. That leads to selecting of
not completely matching tx_burst routine and harms the performance.
This patch introduces the new approach for tx_burst code. It is proposed
to develop the unified template for tx_burst routine, which supports
all the Tx offloads and takes the compile time defined parameter
describing the supposed set of supported offloads. On the base
of this template, the compiler is able to generate multiple tx_burst
routines highly optimized for the statically specified set of
Tx offloads.
Next, in runtime, at Tx queue configuration the best matching optimized
implementation of tx_burst is chosen.
This patch intentionally omits the template internal implementation,
but just introduces the template itself to emboss the approach of
the multiple specially tuned tx_burst routines.

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.

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"

- "txq_mpw_hdr_dseg_en"

Intel® 100/200 Series Chipset platforms reduced the round-trip
latency for the LAN Controller DMA accesses, causing in some high
performance cases a buffer overrun while the I219 LAN Connected
Device is processing the DMA transactions. I219LM and I219V devices
can fall into unrecovered Tx hang under very stressfully UDP traffic
and multiple reconnection of Ethernet cable. This Tx hang of the LAN
Controller is only recovered if the system is rebooted. Slightly slow
down DMA access by reducing the number of outstanding requests.
This workaround could have an impact on TCP traffic performance
on the platform. Disabling TSO eliminates performance loss for TCP
traffic without a noticeable impact on CPU performance.
