Hi, Guys
When I run virtio-net-pmd in VM, I got "virtio-net device is already
used by another driver" error message, after I removed the virtio-net.ko, it
worked, but now I cannot use the virio-net driver for another virtual NIC,
this cost that normal network performance(non-DPDK application)
Hi, Guys
I am using DPDK for the packet transmission, but rte_eth_tx_burst() seems
drops too many packets, the NIC is 82574, anyone to help, thanks a lot.
also, does DPDK has a reliable TX API for no packet drop?
Best Regard
John Gong
Thanks, Bruce, it's a good sample.

Hi, guys
Can dpdk support allocate mempool and create ring in kernel level? I know
dpdk is user space driver, but many application need a channel to transmit
data from kernel to user space without any hardware dependency(just like pf
ring)? Anyone has a sample like this?

Thanks, Helin, I got it.

Hi, Hiroshi
I just start to learn DPDK and memnic, in memnic guide, you said "On
host, the shared memory must be initialized by an application using memnic",
I am not so clear that how to initialize the share memory in host, do you
means use posix API or DPDK API to create the share memory?(it

Hi,
Can anyone give some guide about how to run l2fwd-ivshmem, I run host
binary by "host -c 7 -n 3", but got "EAL: No free hugepages reported in
hugepages-2048kB", how can I make l2fwd-ivshmem work? Another question, is
the guest receive data from host binary?

Hi, guys
I found that the ivshmem are supported in DPDK 1.6 but has no any
document about it, how do I use ivshmem? I remember that we must use a
patched qemu binary for enabling ivshmem support in OVDK, does DPDK 1.6 also
need do this? Also, where can I find some ivshmem docs?
