These are a few of the driver updates we've been working on internally.
These clean up a few mismatched struct comments, add checking for dead
firmware, fix an initialization bug, and change the Rx buffer management.
These are based on net-next v5.4-rc3-709-g985fd98ab5cc.

The AdminQ is fine for sending messages and requests to the NIC,
but we also need to have events published from the NIC to the
driver. The NotifyQ handles this for us, using the same interrupt
as AdminQ.

Add the Rx filtering and rx_mode NDO callbacks. Also add
the deferred work thread handling needed to manage the filter
requests outside of the netif_addr_lock spinlock.

Add both the Tx and Rx queue setup and handling. The related
stats display comes later. Instead of using the generic napi
routines used by the slow-path commands, the Tx and Rx paths
are simplified and inlined in one file in order to get better
compiler optimizations.

Most of the NIC configuration happens through the AdminQ message
queue. NAPI is used for basic interrupt handling and message
queue management. These routines are set up to be shared among
different types of queues when used in slow-path handling.

When the netdev gets a new name from userland, pass that name
down to the NIC for internal tracking.

The LIF is the Logical Interface, which represents the external
connections. The NIC can multiplex many LIFs to a single port,
but in most setups, LIF0 is the primary control for the port.

The ionic device has a small set of PCI registers, including a
device control and data space, and a large set of message
commands.
Also adds new DEVLINK_INFO_VERSION_GENERIC tags for
ASIC_ID, ASIC_REV, and FW.

Add in the detailed statistics for ethtool -S that the driver
keeps as it processes packets. Display of the additional
debug statistics can be enabled through the ethtool priv-flags
feature.

Set up the infrastructure for managing Rx filters. We can't ask the
hardware for what filters it has, so we keep a local list of filters
that we've pushed into the HW.

This patch adds a basic driver framework for the Pensando IONIC
network device. There is no functionality right now other than
the ability to load and unload.

- cut down on some unnecessary log messaging
- cleaned up ionic_get_link_ksettings
- cleaned up other little code bits here and there
Shannon Nelson (19):
devlink: Add new info version tags for ASIC and FW
ionic: Add basic framework for IONIC Network device driver
ionic: Add har
The current tag set is still rather small and needs a couple
more tags to help with ASIC identification and to have a
more generic FW version.
