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.

Fix receive loop, enable turbo mode, checksum offloading still needs

The Raspberry PI now copies at 2MByte/s with scp and 4MByte/s with NFS.
