https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=287344 --- Comment #7 from Gleb Smirnoff <glebius@FreeBSD.org> --- IMHO, the kern.ipc.mb_use_ext_pgs was set 1 to one prematurely. This is a raw feature that conflicts not only with ipfw, but with bpf(4), too. I'm afraid there are more conflicts :( We need to make a sweep over many kernel modules to call mb_unmapped_to_ext() when kernel needs to read into unmapped mbuf. We also should have a counter to count such events and provide some kind of feedback to the user that their setup is not benefiting from unmapped mbufs. -- You are receiving this mail because: You are the assignee for the bug.home | help
