Please can a I have volunteers for a code review of the new Solarflare 
Solarstorm 10G ethernet driver for OpenSolaris?

The review materials are posted at http://cr.opensolaris.org/~pdurrant. 
They are split up into several patches:

ip.webrev
---------

Modifications to IP to avoid clobbering multi-fragment packets on the 
receive side.

linkprop.webrev
---------------

Modifications to add properties and statistics for 10G ethernet

sfxge.webrev
------------

The new driver code and some supporting modifications *

stream.webrev
-------------

Implementation of PSARC 2008/539

streamio.webrev
---------------

Modification to avoid bogus pulling up of multi-fragment packets on the 
receive side.

* - The driver, as you will see, is quite large. However it is split 
logically into two halves:

- Files under usr/src/uts/common/io/sfc/efx are part of an OS agnostic 
framework which we use to drive the Solarstorm NICs on Solaris, Windows 
and DOS (yes, DOS).
- Files under usr/src/uts/common/io/sfc/sfxge are Solaris specific and 
use the API provided by the efx code to interface between Solaris' GLD 
and the hardware.

There are also a couple of modifications to existing files:

- An extra DTRACE_PROBE5 in usr/src/uts/common/sys/sdt.h
- Extra inlines to provide pre-fetching on x86 platforms

Please let me know if you are willing to participate in the review as I 
need to make sure I have adequate coverage of all source modules.

Regards,

   Paul
