Hi.
I've been trying to do some benchmarks for NFS over RDMA and I seem to only get
about half of the bandwidth that the HW can give me.
My setup consists of 2 servers each with 16 cores, 32Gb of memory, and Mellanox
ConnectX3 QDR card over PCI-e gen3.
These servers are connected to a QDR IB
The following patchset adds support for running TIPC over InfiniBand.
The patchset consists of three parts (+ a minor fix for the ethernet media
type):
- Preparation: removal of an the unused str2addr callback and move of the
bcast_addr from struct tipc_media to struct tipc_bearer. This is

Some network protocols, like InfiniBand, don't have a fixed broadcast
address but one that depends on the configuration. Move the bcast_addr
to struct tipc_bearer and initialize it with the broadcast address of
the network device when the bearer is enabled.

Support TIPC in the IPoIB driver. Since IPoIB now keeps track of its own
neighbour entries and doesn't require the packet to have a dst_entry
anymore, the only necessary changes are to:
- not drop multicast TIPC packets because of the unknown ethernet type
- handle unicast TIPC packets similar to
The skb-protocol field is used by packet classifiers and for AF_PACKET
cooked format, TIPC needs to set it properly.
Fixes packet classification and ethertype of 0x in cooked captures:

On my Fedora Rawhide boxes, I noticed I was getting warnings saying
that Infiniband modules were not checking for DMA mapping errors. I
wrote this patch to silence the warnings.

That's probably because of a cache line miss.
The thing I don't really understand is that normally, the first cache
line (64 bytes) contains both the Ethernet header and IPv4 header.
So what does this adapter in this respect ?
I guess you should try to use IPOIB_UD_HEAD_SIZE=64 to use the

I guess we would have to change our allocation to __get_free_page()
(instead of alloc_page()), so that we make sure never to get a highmem
page?
Other than that, seems
alloc_page(GFP_ATOMIC) is safe. it doesnt give you a highmempage
Not sure about header splitting. If done, it probably should be smart
as you said (allowing small frames to be in the first part)
