[PATCH net-next v2 4/4] virtio-net: initial debugfs support, export mergeable rx buffer size
...r_netdevice().
(2) Declare an attribute group containing the mergeable_rx_buffer_size
attribute in virtio-net, and initialize the per-netdevice group pointer
to the address of this group in virtnet_probe before register_netdevice
(3) In net-sysfs, modify net_rx_queue_update_kobjects
(or rx_queue_add_kobject) to call sysfs_create_group on the
per-netdev attribute group (if non-NULL), adding the attributes in
the group to the RX queue kobject.
That should allow us to have per-RX queue attributes that are
device-specific. I'm not a sysfs expert, but it seems that rx_queue_ktype

Actually, I reverted, please resubmit this series with the following
build warning corrected:
net/core/net-sysfs.c: In function ?rx_queue_add_kobject?:
net/core/net-sysfs.c:767:21: warning: ignoring return value of ?sysfs_create_group?, declared with attribute warn_unused_result [-Wunused-result]

[PATCH net-next v4 1/6] net: allow > 0 order atomic page alloc in skb_page_frag_refill
skb_page_frag_refill currently permits only order-0 page allocs
unless GFP_WAIT is used. Change skb_page_frag_refill to attempt
higher-order page allocations whether or not GFP_WAIT is used. If
memory cannot be allocated, the allocator will fall back to
successively smaller page allocs (down to order-0 page allocs).
This change brings skb_page_frag_refill in line with the existing
page allocation

[PATCH net-next v2 4/4] virtio-net: initial debugfs support, export mergeable rx buffer size
Hi Jason, Michael
Sorry for the delay in response. Jason, I agree this patch ended up
being larger than expected. The major implementation parts are:
(1) Setup directory structure (driver/per-netdev/rx-queue directories)
(2) Network device renames (optional, so debugfs dir has the right name)
(3) Support resizing the # of RX queues (optional - we could just export
max_queue_pairs files and

[PATCH net-next v5 0/6] virtio-net: mergeable rx buffer size auto-tuning
The virtio-net device currently uses aligned MTU-sized mergeable receive
packet buffers. Network throughput for workloads with large average
packet size can be improved by posting larger receive packet buffers.
However, due to SKB truesize effects, posting large (e.g, PAGE_SIZE)
buffers reduces the throughput of workloads that do not benefit from GRO
and have no large inbound packets.
