The Qlogic Everest Driver for Ethernet(QEDE) Poll Mode Driver(PMD) is
the DPDK specific module for QLogic FastLinQ QL4xxxx 25G/40G CNA family
of adapters as well as their virtual functions (VF) in SR-IOV context.
This patch adds QEDE PMD, which interacts with base driver and
initialises the HW.
This patch content also includes:
- eth_dev_ops callbacks
- Rx/Tx support for the driver
- link default configuration
- change link property
- link up/down/update notifications
- vlan offload and filtering capability
- device/function/port statistics
- qede nic guide and updated overview.rst
Note that the follow on commits contain the code for the features mentioned
in documents but not implemented in this patch.

Changed symbol on NIC overview table from X to Y to help
clarify the indicated features are supported. The X caused
confusion for some readers.
Also, added * character to indicate partially supported
features. This can be used in the future to direct the reader
to more specific details in the individual NIC guides.

Enable "other kdrv" because both NICs require kernel support to work.
Unicast and multicast MAC filters are also enabled as both address types can
be filtered on through the MAC add/remove/set callbacks.

Environment variable MLX5_PMD_ENABLE_PADDING enables HW packet padding
in PCI bus transactions.
When packet size is cache aligned and CRC stripping is enabled, 4 fewer
bytes are written to the PCI bus. Enabling padding makes such packets
aligned again.
In cases where PCI bandwidth is the bottleneck, padding can improve
performance by 10%.
This is disabled by default since this can also decrease performance for
unaligned packet sizes.

Secondary processes are expected to use queues and other resources
allocated by the primary, however Verbs resources can only be shared
between processes when inherited through fork().
This limitation can be worked around for TX by configuring separate queues
from secondary processes.

The patch introduces a new PMD. This PMD is implemented as thin wrapper
of librte_vhost. It means librte_vhost is also needed to compile the PMD.
The vhost messages will be handled only when a port is started. So start
a port first, then invoke QEMU.
The PMD has 2 parameters.
- iface: The parameter is used to specify a path to connect to a
virtio-net device.
- queues: The parameter is used to specify the number of the queues
virtio-net device has.
(Default: 1)
Here is an example.
$ ./testpmd -c f -n 4 --vdev 'eth_vhost0,iface=/tmp/sock0,queues=1' -- -i
To connect above testpmd, here is qemu command example.
$ qemu-system-x86_64 \
<snip>
-chardev socket,id=chr0,path=/tmp/sock0 \
-netdev vhost-user,id=net0,chardev=chr0,vhostforce,queues=1 \
-device virtio-net-pci,netdev=net0,mq=on

Mmap PCI resource file and add inline functions for reading from and
writing to PCI resource address space.
Add description of IBUF and OBUF address space.
Add configuration option for setting which firmware type will be used.
Right address space values for IBUFs and OBUFs offsets are used
according to configuration option CONFIG_RTE_LIBRTE_PMD_SZEDATA2_AS.
Setting link up/down and getting info about link status is done through
mmapped PCI resource address space.

PMD was of type PMD_VDEV which means that PCI device is not recognised
automatically during EAL initialization, but it has to be created by
EAL option --vdev.
Now, PMD is of type PMD_PDEV which means that PCI device is probed
and recognised during EAL initialization automatically.
Path to szedata2 device file is matched with device and the count
of available RX and TX DMA channels is found out during device
initialization.
Initialization, starting and stopping of queues is changed to better
correspond with Ethernet device API model. Function callbacks
(rx|tx)_queue_(start|stop) are added. Unnecessary items are removed
from ethernet device private data structure.

This patch enables reading sglort (global resource tag) info into the
mbuf for RX and inserting an FTAG (Fabric Tag) at the beginning of the
packet for TX. The vlan_tci_outer field selected from rte_mbuf structure
for sglort is not used in fm10k now.
In FTAG based forwarding mode, the switch will forward packets according
to glort info in FTAG rather than mac and vlan table.
To activate this feature, user needs to pass a devargs parameter to eal
for fm10k device like "-w 0000:84:00.0,enable_ftag=1". Currently this
feature is supported only on PF, because FM10K_PFVTCTL register is
read-only for VF.

In interrupt mode, each rx queue can have one interrupt to notify the
application when packets are available in that queue. Some queues
also can share one interrupt.
Currently, fm10k needs one separate interrupt for mailbox. So, only those
drivers which support multiple interrupt vectors e.g. vfio-pci can work
in fm10k interrupt mode.
This patch uses the RXINT/INT_MAP registers to map interrupt causes
(rx queue and other events) to vectors, and enable these interrupts
through kernel drivers like vfio-pci.

The physically linked-together combined library has been an increasing
source of problems, as was predicted when library and symbol versioning
was introduced. Replace the complex and fragile construction with a
simple linker script which achieves the same without all the problems,
remove the related kludges from eg mlx drivers.
Since creating the linker script is practically zero cost, remove the
config option and just create it always.
Based on a patch by Sergio Gonzales Monroy, linker script approach
initially suggested by Neil Horman.
