Merge branch 'ionic-updates' 

Shannon Nelson says:

====================
ionic updates

This set of patches is a bunch of code cleanup, a little
documentation, longer tx sg lists, more ethtool stats,
and a couple more transceiver types.

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.
