Hi Andrew and Gavin,
To flesh out Andrew's commit message, and add some surrounding detail to
help in debugging:
Before 527d10ef3a315, all PEs were unfrozen when we called
eeh_reset_device(). That patch changed behaviour to skip the PE
associated with or reserved for the PHB. Indeed, this shouldn

No way.
We have every conceivable implementation of CRC calculations in the
kernel already. Use them.

Allow the selection of the transmission queue based on the CPU id.
The DPAA Ethernet driver defines a ndo_select_queue() callback for
optimal selection of the egress FQ. That will override the XPS support
for this netdevice and should provide a certain increase in performance.
Standard XPS support

Prototypes for sys_ni_syscall and sys_call_table are available
in header files, so remove the prototypes in c code.
This was noticed when building with -flto, because the prototype for
sys_ni_syscall doesn't match the function and we get a compiler error.
