Hello,
Issue observed when using vmxnet3 based interface on packet with following
structure is sent:
Ethernet + PPPoE + PPP (22 bytes) as the Layer 2 header,
IPv4 (20)
UDP
DNS Payload
The tx offload value in this case is 0x0f0 (PKT_TX_IPV4 |
PKT_TX_IP_CKSUM | PKT_TX_UDP_CKSUM)
Hi,
Does anyone have a work-around for this? Should we debug the vmxnet3 driver
since for sure this issue is even coming in standard l2fwd example.
Thanks,
Padam

the ether type values are not printed byte-swapped … so it’s 8100 (VLAN) and
0800 (IPv4).

If I redo the test with the same physical and vmware setup but instead of
vmxnet3 I use e1000e emulation driver, all of this works fine. Packets come
properly stripped of VLAN with vlan_tci fields set correctly.

Hi,
When configuring the vmxnet3 based ethernet device, the RX VLAN Strip offload
does not work as it usually does with other real NICs which support this
function.
When configuring with rxmode.hw_vlan_strip = 1, the ipackets statistic does not
increase when a VLAN ether type frame is received

Hi,
I am crafting a packet in which the source MAC address as set in the Ethernet
header is different than the transmit port?s default MAC address. A packet
capture of the packets coming out of this port however comes with source MAC
address of the port?s default MAC address.

Hi,
I was reading up on the Xeon Phi processors - up to 61 cores?.. looks very
interesting. Has anyone tried offloading packet processing to such a
co-processor utilising the existing code base?

Hi,
While implementing a sample packet generation code, I am setting up the offload
flags so that the hardware (82599ES in my case) computes the IP and TCP
Checksums. However, it seems that only the IP checksum is computed whereas the
TCP Checksum is computed, but computed wrong. Here is a snip
Hello,
I have an application which in which the rte_mempool for packets associated
with the network interfaces using IXGBE and IGB drivers is depleting slowly.
Each time I do a throughput test, the number of free_count keeps reducing by
10-15 entries, and finally completely exhausts.
Any input
Thanks Marc, Matt, Kyle, and Stephen for your inputs!
I have a possibly good solution of splitting the mbuf into parts to correctly
mirror to multiple interfaces, else a fallback of copying the full payload into
a new mbuf.
Though the library doesn?t offer a standard method to copy, I can submi
Hello,
Is there a function in DPDK to completely clone a pkt_mbuf including the
segments?
I am trying to build a packet mirroring application which sends packet out
through two separate interfaces, but the packet payload needs to be altered
before send.

Hello,
I have done a simple mbuf adjust and prepend to achieve the removal and
insertion of the vlan header and it works fine. The use case is something
similar to the l3fwd example where one port has traffic coming in on multiple
vlans and the other port has no vlans. The packet processing pa
