Dear Vlad: Unfortunately, no. The code seems stable in 8-CURRENT, but I don't feel it's had enough actual testing exposure to go into 7.x yet. Also, the libpcap changes to support it have only just gone back into the tcpdump.org distribution of libpcap, and there is non-trivial reworking of that code, so we'd like to let that settle as well. We've had a number of queries so I suspect we'll start maintaining a 7.x MFC candidate patch fairly soon (next couple of months). Robert N M Watson Computer Laboratory University of Cambridge
