While attempting to run tshark to extract specific a11/a10 informtion out from
a large pcap file, I continue to get the following WARNING message.  This slows
down the extraction process.

1) Is there a way to ignore these messages?  I can't send them to /dev/null
because I need to extract the desired output to STDOUT.

2) Is there a fix for these WARNING - 'failed assertion' problems?


COMMAND RUN:
 PDSNControlIp=$(tshark -c $numpackets -V -r $1 a11 | grep -A12 "Registration
Request" | grep "Home Agent:" | cut -d':' -f2 | cut -d' ' -f2 | sort | uniq |
awk '{if (NR==1) printf "%s", $0; else printf ",%s",$0;}')
