Re: [dpdk-dev] Intel 82571EB PMD support

[Chetan Bali <chetan.bali@aricent.com>]

Hi,
Have checked this file too. It's listed and also init of pmd is fine and working since link is up.

After sending the packets from directly connected interface, we are seeing that rx nic stats are increasing but
We are not seeing descriptor done status ( E1000_RX_STAT_DD ) set hence it is not able to get the packet from rx software ring.

Since the link is up, it should be able to receive the packets. Can anyone help resolve this issue?

Thanks & Regards
Chetan Bali

Hi,

Do we have PMD support for intel 82571EB. We are having e1000e driver supported for 82571EB in linux.

DPDK Version : 1.6.0-r1

Linux Kernel : CentOS 6.4 [ kernel version 2.6.32-358.el6.x86_64 ]


Issue:

When we run DPDK example [ l2fwd ], we are able to see successful init of rte_pmd_em and link is also detected successfully.
But the RX, TX count are zero. If we try to fetch nic stats using rte_eth_stats_get(), we can see around 256 ipacket count but after that error count [rx error ] starts increasing.

We are not able to see any packet on user app [ l2fwd ]. Does anyone else face the same issue?

Regards
Chetan Bali
