Not sure to understand your request.
Are you looking for that?

Hello list,
For some time I've been writing a custom packet generator coupled with a
packet receiver using DPDK.
It works greatly when used for generating millions of packets, but
unexpectedly It has troubles generating a several dozens of packets or so.
The application consists of two thread

Thomas,
If I use hugetlbfs the VM does not crash and it works as
expected. This is good enough and unblocks me. Thanks for the help.

Hi,
We are using Windriver PktGen to replay PCAP packet captures.
Is there a way to specify source/destination IP range to use while
replaying PCAP packet captures? If not, is there a plan to add such feature
in future?
Thanks

I am looking for spinlocks that use a single bit (bit 31) of a 32 bit word for
locking. The rest of the bits in the word are left undisturbed. This enables
more compact data structures as only 1 bit is consumed for the lock.
Thanks
Pash

Hi,
We use bit spinlocks extensively to have compact data structures. Are there
any plans for adding them to DPDK in some future release?
Thanks

Fix pcap build - In rte.sdkbuild.mk with CONFIG_RTE_LIBRTE_PMD_PCAP=y,
we error-exit if LIBPCAP_CFLAGS is empty. On some distros (e.g., Centos
6.4),
it is normal for "pcap-config --cflags" to output only a newline, because

RSS is a way to distribute packets to multi cores while packets order in
the same flow still get maintained.
Round robin distribution of packets may cause ooo(out of order) of packets
in the same flow.
We also meet this problem in ipsec vpn case.

Hi,
Regarding this point ?C
If intel supports round robin distribution of packets in the same flow, Intel
needs to provide some way like Cavium's SSO(tag switch) to maintain packet
order in the same flow. And it is hard to do so because intel's cpu and nic are
decoupled
My main submission is
Can we (as a community) be leading the way for the NIC vendors?
I mean, a few years ago I had the discussion with Chelsio to solve MPLS and GTP
load balancing.
They were happy to integrate the "requirements" in the roadmap
So could we build a list of such "requirements" and publish it? NIC v
