## Summary Capturing Ethercat Canopen over Ethercat Mailbox Communication is encoded incorrectly. ## Steps to reproduce Capture communication between Ethercat Master and COE capable slave. ## What is the current bug behavior? Instead of decoding value 8 for **SDO Information** in the COE Header, it is shown as **Type: Unknown** ## What is the expected correct behavior? It should show **SDO Information** ## Sample capture file [coe.pcapng](/uploads/baa0806a92be1ba7c0212078509c3ce3/coe.pcapng) ## Relevant logs and/or screenshots  ## Build information 3.6.5 (v3.6.5-0-g21f79ddbefbd) Compiled (64-bit) using Microsoft Visual Studio 2019 (VC++ 14.31, build 31107), with Qt 5.15.2, with libpcap, with GLib 2.66.4, with zlib 1.2.11, with Lua 5.2.4, with GnuTLS 3.6.3 and PKCS #11 support, with Gcrypt 1.8.3, with MIT Kerberos, with MaxMind DB resolver, with nghttp2 1.44.0, with brotli, with LZ4, with Zstandard, with Snappy, with libxml2 2.9.10, with libsmi 0.4.8, with QtMultimedia, with automatic updates using WinSparkle 0.5.7, with AirPcap, with SpeexDSP (using bundled resampler), with Minizip.
