Subject: app/testpmd: fix MAC header in csum forward engine
|
|
|
|
[ upstream commit 008834b91ac9a9e4ea982e5d2a4526d1b90a8d18 ]
|
|
|
|
MLX5 SR-IOV Tx engine will not transmit Ethernet frame
|
|
if destination MAC address matched local port address. The frame ether
|
|
looped-back to Rx or dropped, depending on the port configuration.
|
|
|
|
Application running over MLX5 SR-IOV port cannot transmit packet
|
|
polled from Rx queue as is. The packet Ethernet destination address
|
|
must be changed.
|
|
|
|
Add new run-time configuration parameter to the `csum` forwarding
|
|
engine to control MAC addresses configuration:
|
|
|
|
testpmd> csum mac-swap on|off <port_id>
|
|
|
|
`mac-swap on` replace MAC addresses.
|
|
`mac-swap off` keep Ethernet header unchanged.
|
|
|
|
Fixes: 9b4ea7ae77fa ("app/testpmd: revert MAC update in checksum forwarding")
