23820a7989 net/mlx5: rename hash RxQ verbs to general
Prepare for introducing use of DevX TIR object.
Hash Rx queue is currently created using verbs QP only.
The next patches will add the option to create it with a TIR object
using DevX.
This patch renames hrxq_ibv to hrxq wherever relevant, and adds
the DevX items to relevant structs.

21cae8580f net/mlx5: allocate door-bells via DevX
When using DevX API, memory for door-bell records should be allocated
by PMD and registered using DevX API.

This patch implements the utility functions to support it:
- Add struct mlx5_devx_dbr_page, containing door-bells page data.
- Add list of struct mlx5_devx_dbr_page door-bell pages to device
  private data.
- Implement function mlx5_alloc_dbr_page() to allocate page for
  door-bell records, and register it using DevX API.
- Implement function mlx5_get_dbr(). to acquire a door-bell record
  from the door-bells page, allocating a new page if needed.
- Implement function mlx5_release_dbr() to release a door-bell
  record that is no longer needed, freeing the containing page if
  it becomes empty.

d34db5ccbf net/octeontx2: fix driver reconfiguration
When configure returns error, e.g. in case not supported offloads
(outer ip and sctp) driver released Rx,Tx queues. Then in case of
correct configuration the driver could not start due to queues already
released but the driver thought it was configured correctly.

Secondly if driver returns error from configuration librte_ethdev will
release, rx queues and tx queues, without chaining driver configured
state.

Fix that by 'releasing' configuration and changing driver state when
error is returned from otx2_nix_configure.

fa2e14d492 net/mlx5: cache associated network device index
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.

eb8121ab9d net/mlx5: introduce Tx burst routine template
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.

  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.

- 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.

f0027fa182 net/e1000: fix buffer overrun while i219 processing DMA
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.

Please, refer to I218/I219 specification update:
https://www.intel.com/content/www/us/en/embedded/products/networking/
ethernet-connection-i218-family-documentation.html

fca922e8f6 net/bnxt: disable vector mode Tx with VLAN offload
The vector mode transmit path does not currently support VLAN tag
insertion, so we need to disable vector transmit when transmit
VLAN insertion offload is enabled.

b4e190d55c net/bnxt: fix MAC/VLAN filter allocation
We were adding the VLAN filters to all the VNICs of the function.
Also, we were adding these VLANs to all the existing MAC only filters.
This was resulting in fewer VLANs getting added. By default we should
allocate MAC+VLAN filter only to the default VNIC of the function using
the default mac address.
Similar logic was followed in the VLAN deletion code. This patch fixes
it.  Use inner VLAN fields instead of outer VLAN during filter deletion
to be in sync with VLAN addition code.
