Subject: [PATCH] ns83820.c v0.15

Hey Marcelo,

Here's my update to the ns83820 driver with the patches from Jeff Garzik for
cleanups and ethtool support, plus the optical support from Michael Clark.
It's tested and working fine. More updates are pending, but for now this
is useful to a number of people. Please apply. Thanks,

-ben
