[dpdk-users] Facing failure with enabling macsec in 82599EB

[gaurav maheshwari]

Hi,

We are try  to enable macsec on Intel nic 82599EB, we are facing failure in
doing so.
While enabling the macsec in testpmd, in rx side we are seeing 4 bytes
missing.
This behavior  is not seen when macsec is disabled.

I am adding below pdump output to show the tx and rx dump.

*TX SIDE:*

./dpdk-pdump    --file-prefix=tx  -w  0000:87:00.0  --      --pdump
'port=0,queue=*,tx-dev=/tmp/capture.pcap'
