[PATCH 3/3] net: e1000: Add missing address translations

[Stefan Roese]

Add some missing address translations from virtual address in local DRAM
to physical address, which is needed for the DMA transactions to work
correctly.

This issue was detected while testing the e1000 driver on the MIPS
Octeon III platform, which needs address translation.
