I' don't know if it is a bug of driver or ipfw or jail virtualization. I wrote only a message on the net-list and to original writer (freebsd@intel.com), but i don't receive any reply. I want to do other tests to determinate more precisely nature of bug, but servers who I reproduce the problem is a production server (!) and I have no time (!!!) to do this. Sorry.
