Thanks Michael !

It really does improves the speed, great :-).

Unfortunately, I am seeing about once a day a panic (uvm_fault) and the 
RPI thus is much less stable than before.

The stack trace I could hand copy is:

Trap in m_xhalf+0x9c

bt gave:

bpf_filter_ext+0xc
_bpf_mtap+0x278
smsc_rxeof+0x11c
usb_transfer_complete+0x2d4
dwc2_softintr+0x90
usb_softintr+0x28
softint_dispatch+0xec

I'll now backout the change to see whether the panics disappear.

Frank
