Thanks Paul, I worried about mixing branches since I've never tried that
before.  The only reason I picked Denzil is because I need ti816x support
and Dylan and Danny don't have machine confs for it in meta-ti.  So what
would be easier, getting the machine support I need in Dylan or back
porting the net-snmp recipe to Denzil?
