Macsec on T1024

Hello,

I am trying to set up encrypted communication between two T1024RDB via MacSec.

modprobe fsl-dpa-macsec ifs="fm1-mac4"

gives me

/sys/kernel/debug/powerpc/fsl_macsec_dpa/fm1-mac4

/sys/module/fsl_dpa_macsec

HostAP and wpa_supplicant establish connection (see screenshot)

I assigned ip adresses to fm1-mac4 ports on both machines and sent data between the two boards but it wont start encrypting anything going over those ports.

Can you explain how it was discovered that there was no encryption?

Can you provide a full console log, with all messages generated by u-Boot and Linux, all setup and diagnostic commands

you issued and the system reaction to them?

Hello,

I am using a hilscher netAnalyzer between my two boards to check their communication so i can see if it was encrypted or not.

The complete Log is attached, note that i use ethtool to set 100mbs so i can use the netanalyzer and "disassociated/deauthenticated due to inactivity" also happens if i continuesly ping the other system so Im guessing that connections not being used.

Much appreciated,

Florian
