MCU-PLUS-SDK-AM243X: EtherNet/IP Adapter Demos: LLDP Management Object Test

I built the demo below and checked its operation.

"ethernetip_adapter_generic_device_mii_demo_am243x-lp_r5fss0-0_freertos_ti-arm-clang"

We checked with version 09.00.00.03 of INDUSTRIAL-COMMUNICATIONS-SDK-AM243X.

We then conducted a CT19.1 protocol test on these.

At that time, the following error occurred in LLDP Management Object Test.

1323      1> *** The required System Capbility TLV is missing.
1324      2> *** The required Management Address TLV is missing.
1325      3> *** The required CIP Identification TLV is missing.

Although it is a shutdown LLDP frame, it seems that the packet size remains unchanged at 100 bytes.

When I checked the Known Issues, I found the following issues.

[DTKEIPA-1838]
Sporadic LLDP error reported by CT19.1 after changing msgTxInterval.
The ODVA Conformance Test sets the LLDP msgTxInterval (Instance Attribute 2 in LLDP Management Object) to 5 seconds. After that the DUT correctly transmits a LLDP frame immediately (see IEEE802.1 chapter 9.2.10 Transmit timer state machine). The subsequent LLDP frame is occasionally not send correctly after 5 seconds.

Is the above error related to Known Issues?

Also, will it be fixed in the next release?
