Suricata

During some tests I have noticed that Suricata parses all the yaml variable in a particular way:

If the variable is lexically correct - no problem. If it is not Suricata silently defaults to the default value.

I did some more test with 1.4.5 and latest git on more yaml variable
and the results are generally the same. One such example -

max-pending-packets: 4096o

Notice the wrongly put letter "O" instead of zero "0" at the end. In this cases Suricata silently defaults to the default 1024 packets.

value:
<Info> - preallocated 1024 packets. Total memory 4362240

I believe this is a general issue with most of the variable parsing from suricata.yaml

Thanks
