Well, I don't really know that hardware in detail. I just browsed the
code, e.g:
http://git.kernel.org/?p=linux/kernel/git/davem/net-next-2.6.git;a=commit;h=38c845c76
http://marc.info/?l=linux-netdev&m=126389931509102&w=2
But I believe that your interface is generic enough to support that
hardware as well. Would make sense to put the relevant people on CC and
also "ptpd@lists.infradead.org."
Wolfgang.
