I am using BPF filter to capture Qnet packets and can do it successfully when I compile separate executable. Now I am 
trying to do same thing in a shared library to add an new option for lsm-qnet.so - resolve=myresolve. Here I am using 
nr_template.c in ..../lsm/qnet/doc/ directory and building my shared library nr-myresolve.so. In this the open fails 
when trying to open /dev/bpf0 in read only mode. Can any one help me to get the thing working?
