Precedence: bulk

There are subtle differences between the 82598 and 82599 devices.

A quick skim of our driver and the datasheets show at least two
differences:

- the Ral and Rah registers used to set up the receive MAC address
have different addresses (0x540[48] on the 82598 and 0xa20[04]
on the 82599),

- and the Rdrxctl register is at the same address but has different
contents.

For both of those, our driver only uses the 82598 style registers.
There are probably more as well. I don't have the time to fix this
but it shouldn't be too difficult. Have fun.

Cheers,
  Anthony
