docs: networking: reorganize driver documentation again

Organize driver documentation by device type. Most documents
have fairly verbose yet uninformative names, so let users
first select a well defined device type, and then search for
a particular driver.

While at it rename the section from Vendor drivers to
Hardware drivers. This seems more accurate, besides people
sometimes refer to out-of-tree drivers as vendor drivers.

-Identifying the Adapter
-=======================
-
-To find if one or more Pensando PCI Ethernet devices are installed on the
-host, check for the PCI devices::
-
-  $ lspci -d 1dd8:
-  b5:00.0 Ethernet controller: Device 1dd8:1002
-  b6:00.0 Ethernet controller: Device 1dd8:1002
-
-If such devices are listed as above, then the ionic.ko driver should find
-and configure them for use.  There should be log entries in the kernel
-messages such as these::
-
-  $ dmesg | grep ionic
-  ionic 0000:b5:00.0: 126.016 Gb/s available PCIe bandwidth (8.0 GT/s PCIe x16 link)
-  ionic 0000:b5:00.0 enp181s0: renamed from eth0
-  ionic 0000:b5:00.0 enp181s0: Link up - 100 Gbps
-  ionic 0000:b6:00.0: 126.016 Gb/s available PCIe bandwidth (8.0 GT/s PCIe x16 link)
-  ionic 0000:b6:00.0 enp182s0: renamed from eth0
-  ionic 0000:b6:00.0 enp182s0: Link up - 100 Gbps
-
-Driver and firmware version information can be gathered with either of
-ethtool or devlink tools::
-
-  $ ethtool -i enp181s0
-  driver: ionic
-  version: 5.7.0
-  firmware-version: 1.8.0-28
-  ...
-
-  $ devlink dev info pci/0000:b5:00.0
-  pci/0000:b5:00.0:
-    driver ionic
-    serial_number FLM18420073
-    versions:
-        fixed:
-          asic.id 0x0
-          asic.rev 0x0
-        running:
-          fw 1.8.0-28
-
-See Documentation/networking/devlink/ionic.rst for more information
-on the devlink dev info data.
-
-Enabling the driver
-===================
-
-The driver is enabled via the standard kernel configuration system,
-using the make command::
-
-  make oldconfig/menuconfig/etc.
-
-The driver is located in the menu structure at:
-
-  -> Device Drivers
-    -> Network device support (NETDEVICES [=y])
-      -> Ethernet driver support
-        -> Pensando devices
-          -> Pensando Ethernet IONIC Support
-
-Configuring the Driver
-======================
-
-MTU
----
-
-Jumbo frame support is available with a maximim size of 9194 bytes.
-
-Interrupt coalescing
---------------------
-
-Interrupt coalescing can be configured by changing the rx-usecs value with
-the "ethtool -C" command.  The rx-usecs range is 0-190.  The tx-usecs value
-reflects the rx-usecs value as they are tied together on the same interrupt.
-
-SR-IOV
-------
-
-Minimal SR-IOV support is currently offered and can be enabled by setting
-the sysfs 'sriov_numvfs' value, if supported by your particular firmware
-configuration.
-
-Statistics
-==========
-
-Basic hardware stats
---------------------
-
-The commands ``netstat -i``, ``ip -s link show``, and ``ifconfig`` show
-a limited set of statistics taken directly from firmware.  For example::
-
-  $ ip -s link show enp181s0
-  7: enp181s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
-      link/ether 00:ae:cd:00:07:68 brd ff:ff:ff:ff:ff:ff
-      RX: bytes  packets  errors  dropped overrun mcast
-      414        5        0       0       0       0
-      TX: bytes  packets  errors  dropped carrier collsns
-      1384       18       0       0       0       0
-
-ethtool -S
-----------
-
-The statistics shown from the ``ethtool -S`` command includes a combination of
-driver counters and firmware counters, including port and queue specific values.
-The driver values are counters computed by the driver, and the firmware values
-are gathered by the firmware from the port hardware and passed through the
-driver with no further interpretation.
