I assume that in Linux, 'txqueuelen' actually refers to the maximum (bounded) size of the device's transmit queue before Linux's equivalent of the IFF_OACTIVE flag is set (device transmit queue full and no more data may be queued). The short answer is no. The long answer is it depends; some device drivers offer a means of doing so, but it's not standard by any means. Most network interfaces in FreeBSD set their if_snd.ifq_maxlen to IFQ_MAXLEN, which is 50 by default. In some cases the device driver won't permit you to touch this value because it's hardcoded to match the size of a descriptor ring which the chip uses for data transmission.
