It's been a while since I looked into rsyslog filtering (which isn't 
found in the original syslogd), so I'd recommend you RTFM...  But here's 
an example I did set up some time ago to suppress messages from an 
overly-chatty Avahi daemon...

/etc/rsyslog.d/avahi.conf:

# Not interested in this noise from avahi...
if $programname == 'avahi-daemon' and $msg contains 'Invalid response 
packet from host' then ~
if $programname == 'avahi-daemon' and $msg contains 'with invalid source 
port' then ~
if $programname == 'avahi-daemon' and $msg contains 'Packet too short or 
invalid' then ~
if $programname == 'avahi-daemon' and $msg contains 'Invalid legacy 
unicast query packet' then ~

You're welcome!
