Is this a kernel bug or am I supposed to set something?

It's an unfortunate side effect of hardware VLAN acceleration. It
can't be turned off (apart from patching the driver to not advertise
VLAN acceleration support).

I think that enabling VLAN tags shall be at least kernel run-time or boot time
 configurable option.

Oh, the no VLAN tags with bnx2 is a slightly different matter,
I've used the patch

#ifdef BCM_VLAN
        if (!bp->vlgrp && !(bp->flags & ASF_ENABLE_FLAG))
                rx_mode |= BNX2_EMAC_RX_MODE_KEEP_VLAN_TAG;
#else

Thanks,
I have found out that by disabling the ASF/management firmware through Broadcom 
diagnostic utility I get VLAN tags in the packets. I think that it shall be at least documented
in the driver/help. I have no idea for what the ASF is used for in linux.
There shall be a tool or option how to disable it from user space or at boot time or in driver.
