Hi,
I am new to DPDK and i tried searching the archives in case this had been
discussed but couldnt find any references and hence this email:

Hello, folks!
We have execute bunch of tests for receive data with Intel XL710 40GE

capture.
But we definitely can't do it. We tried with different versions of
DPDK: 1.4, 1.6, 1.8, 2.0. And have not success.
We achieved only 40Mpps

Hi all,
I am getting a strange error compiling some RTM instructions when I upgraded my
VM environment from VirtualBox 4 to VirtualBox 5 and AVX instructions from the
host CPU became available. However when I am reading the opcode description for
XABORT it supposedly allows an immediate operand
It would appear there is some bug in the new lock elision patches that is
preventing it from compiling with clang. Any suggestions?

Just a detail: the doc file is added in a later patch.
For consistency, this line should be added later.

It builds with clang.
My suggestion is to add the patch author in recipient's list ;)

This patchset is to replace the existing hash library with
a more efficient and functional approach, using the Cuckoo hash
method to deal with collisions. This method is based on using
two different hash functions to have two possible locations
in the hash table where an entry can be.
So, if a buck
Added reset function to be able to empty the table,
without having to destroy and create it again.

rte_hash structure should not be a public structure,
and therefore it should be moved to the C file and be declared
as internal.
This patch also removes part of a unit test that was checking
a field of the structure.

Previous implementation was lacking a function
to look up a burst of entries, given precalculated hash values.
This patch implements such function, quite useful for
looking up keys from packets that have precalculated hash values
from a 5-tuple key.
Added the function in the hash unit tests as wel
rte_prefetchX functions included volatile void *p as parameter,
but the function does not modify it, so it should include the const keyword.

Usually hash tables not only store keys, but also data associated
to them. In order to maintain the existing API,
the key index will still be returned when
