I am register file descriptor in kevent with EV_SET(ke+used, thr->outside.fd, EVFILT_READ, EV_ADD | EV_ENABLE | EV_CLEAR, 0, 0, &thr->outside); after got event in kevent(kq, NULL, 0, ke, max_event, NULL) I am don't see anything in rxring. if I do ioctl(fd, NIOCRXSYNC, NULL) after kevent I am see received packets in rxring, but nothing transmited. if I do ioctl(fd, NIOCTXSYNC, NULL) before kevent -- packets transmited. I am try this in VirtualBox VM. Also, can you look in this thread about VLAN processing? _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
