The only slightly tricky merge conflict was the netdevsim because the
mutex locking fix overlapped a lot of driver reload reorganization.
The rest were (relatively) trivial in nature.

Even out Rx performance across MTU sizes by changing from full
skb allocations to page-based frag allocations. The device
supports a form of scatter-gather in the Rx path, so we can
set up a number of pages for each descriptor, all of which are
easier to alloc and pass around than the standard kzalloc'd
buffer. An skb is wrapped around the pages while processing
the received packets, and pages are recycled as needed, or
left alone if they weren't used in the Rx.

Most of our firmware has a heartbeat feature that the driver
can watch for to see if the FW is still alive and likely to
answer a dev_cmd or AdminQ request.

Even though we've already turned off the queue activity with

The user's request for an interrupt coalescing value gets
translated into a hardware value to be used with the NIC,
and was getting reported back based on the hw value, which,
due to hw tic resolution, could be reported as a different
number than what the user originally asked for. This code
now tracks both the user request and what was put into the
hardware so we can report back to the user what they
requested.

When no other driver selects the devlink library code, ionic
produces a link failure:
drivers/net/ethernet/pensando/ionic/ionic_devlink.o: In function `ionic_devlink_alloc':
ionic_devlink.c:(.text+0xd): undefined reference to `devlink_alloc'
drivers/net/ethernet/pensando/ionic/ionic_devlink.o: In function `ionic_devlink_register':
ionic_devlink.c:(.text+0x71): undefined reference to `devlink_register'
Add the same 'select' statement that the other drivers use here.

The ionic interrupt model is based on interrupt control blocks
accessed through the PCI BAR. Doorbell registers are used by
the driver to signal to the NIC that requests are waiting on
the message queues. Interrupts are used by the NIC to signal
to the driver that answers are waiting on the completion queues.
