Hi Nicholas,
I love your patch! Perhaps something to improve:

We execute certain NPU2 setup code (such as mapping an LPID to a device

cannot succeed on P8+ machines and errors appear in dmesg. This is
harmless as skiboot returns an error and the only place we check it is
vfio-pci but that

Take advantage of the additional optimizations in netdev_alloc_skb when
allocating socket buffers to be used for packet reception.

If the current NAPI polling loop exits without completing it's
budget, only re-enable interrupts if there are no entries remaining
in the queue and napi_complete_done is successful. If there are entries
remaining on the queue that were missed, restart the polling loop.
Remove unused and superfluous code and members in
existing TX implementation and data structures.

PCI bus slowdowns were observed on IBM VNIC devices as a result
of partial cache line writes and non-cache aligned full cache line writes.
Ensure that packet data buffers are cache-line aligned to avoid these
slowdowns.

Include support for the xmit_more feature utilizing the
H_SEND_SUB_CRQ_INDIRECT hypervisor call which allows the sending
of multiple subordinate Command Response Queue descriptors in one
hypervisor call via a DMA-mapped buffer. This update reduces hypervisor
calls and thus hypervisor call overhead
This patch introduces the infrastructure to send batched subordinate
Command Response Queue descriptors, which are used by the ibmvnic
driver to send TX frame and RX buffer descriptors.

Utilize the H_SEND_SUB_CRQ_INDIRECT hypervisor call to send
multiple RX buffer descriptors to the device in one hypervisor
call operation. This change will reduce the number of hypervisor
calls and thus hypervisor call overhead needed to transmit
RX buffer descriptors to the device.
Update error handling code in ibmvnic_xmit to be more readable
and remove unused statistics counters. Also record statistics
when TX completions are received to improve accuracy.

When firmware reports that a transmission was not successful,
the driver is not correctly processing the completion.
It should be freeing the socket buffer and updating the
device queue's inflight frame count and BQL structures.
Do that now.
Fixes: 032c5e82847a ("Driver for IBM System i/p VNIC
First, memory barrier protection of device queue reads to ensure RX
and TX buffer completions are not missed. The subsequent three
patches utilize a hypervisor call allowing multiple TX and RX buffer
replenishment descriptors to be sent in one operation, which
significantly reduces hypervisor call
It is not longer used, so remove it.
