OpenBSD. Ограничение потока в ALTQ 4 гбит/с

Вряд ли конечно придется попробовать ALTQ на 10-гигабитных интерфейсах, но тем не менее не стоит забывать:

ALTQ using hfsc is limited to a maximum parent bandwidth of 4294Mb.
This value is 2^32 or 4,294,967,296 bits. If you set the bandwidth any
higher, altq will flip back to zero. This “bug” was found when trying
to test 10 gigabit and 40 gigabit bandwidth models. These tests were
done on OpenBSD 32bit and 64bit as well as FreeBSD 32bit and 64bit.
