Hi,
I am using DPDK for SRIOV.
I have one Intel X520 with two PFs.
After binding the two PFs to igb_uio, I create two VFs and assign
them to a virtual machine.
I found that to wake up VF, the VF will send some message to PF
such as IXGBE_VF_SET_MACVLAN(0x06) and IXGBE_VF_API_NEGOTIATE(0x08)
for t
Hi,
In DPDK how should a raw ethernet frame converted to rte_mbuf * ? For
example if I have an ARP packet:
void * arp_pkt
how should this be converted to an rte_mbuf * for transmission, does a
simple cast suffice ?
Cheers,
Pepe

Hi All,
after porting Intel's Data Plan to QNX 6.5 I'm doing some performance
test with "testpmd".
I'm using a single i210 board installed on a dual core QNX 6.5 machine
and using "testpmd" as a packet generator (UDP packets).
The test are done with:
start: testpmd -c 3 -n -> interactive mo
Hi Pepe,
Ofcourse a simple cast will not suffice.
Please look the rte_mbuf structure in the header files and let me know if you
still have the confusion.
There is a header and payload. Your raw frame will go in the payload.

Hi Pepe,
In addition, you may want to consider the frame's lifetime, to ensure memory
is used and released
in a valid way.
When sending, it may be de-referenced by DPDK and consequently a memory free
may be tried.
Hence, it is important that the raw buffer used for the ARP packet is
allocated wit
I see thanks for the tip.
Cheers,
Pepe

Hi,
dpdk folks,
I am working on a project which is offering a complete IO stack for dpdk,
particularly a SCSI target stack in dpdk ? dpdk-iokit, once I finished my
initial code, will upload to github. I would like to know if there is any other
people is working on that purpose?

Hi guys,
I am facing a peculiar issue with the usage of struct rte_mbuf-> ol_flags field
in the rte_mbuf when I receive the packets with the rte_eth_rx_burst function.
I use the ol_flags field to identify whether is an IPv4 or IPv6 packet or not
thus -
if ((pkts_burst->ol_flags & PKT_RX_IPV4_HD
Hi Prashant,
May be it doesn't work due to Known Issues and Limitations (see Release
