thanks for the hint. The controller should support MSI interrupts.

But as I read in https://wiki.freebsd.org/dev/ath_hal%284%29/AR9300, MSI
interrupts are not supported before AR9300 HAL.
So i'll buy an other card and try again.
But it would be a good idea to add the check for supported MSI/MSI-x
interrupts to the https://wiki.freebsd.org/bhyve/pci_passthru .
