Hi,
 
I've attached two captures with a single packet in each.
 
They are both supposed to be syslog events injected into the capture with SLL (Linux cooked capture).
 
On one everthing is decoded as expected in the other with the same first 16 octets it is detected as
Ethernet II only.
 
I cannot figure out why they are not both decoded as SLL/Linux cooked-mode captures.
 
Any thoughts would be greatly appreciated.
 
I'm running on Windows 7 using Wireshark 2.6.1.
The capture was taken on a CentOs 7 box by a tool injecting the "fake" syslog message.
 
BR,
 
Michael
