[nxppenpals]

dear nxp support
I want to use tc command to setup dpsw switching offloads routing actions our LX2160A‑based custom hardware.
But the tc command return below error

Hello @nxppenpal

you need to do some configurations into the kernel before trying to use the tc command.
please review the steps, in the next link, in order to be able use the command:

https://docs.nxp.com/bundle/REALTIMEEDGEUG/page/topics/using_linux_traffic_control_tc.html

I have followed your suggestion. but i get the same error.
tc qdisc add dev eth4 clsact
tc filter add dev eth4 ingress flower src_mac 00:01:02:03:04:05 skip_sw action trap

dear @nxppenpals ,

you need to upgrade to the LLDP 6.1.55 instead to use the LSDK 20.4

Also, please review the chapter "7 QorIQ networking technologies" in the LLDP user guide.

Be aware about the TSN switch hardware, it is present only in the LS1028A

dear @LFGP
Could you please confirm if the dpaa2 dpsw trap functionality is indeed not supported in the standard LSDK 20.04 release?
if upgrading to LLDP 6.1.55 is not feasible for us, is there a specific patch available that we can apply to the current version to enable the dpsw trap feature?

[LFGP]

Dear @nxppenpals,
it is not supported in the LSDK 20.04, instead of , please use the LSDK 21.08 or newer, like the LLDP 6.1.55
best regards
LFGP
