[PATCH] e1000 driver RX race condition fixed

[Dmitry Fleytman]

There is a race condition in e1000 driver.
It enables HW receive before RX rings initalization.
In case of specific timing this may lead to host memory corruption
due to DMA write to arbitrary memory location.
Following patch fixes this issue by reordering initialization steps.

Other Intel network drivers does not seem to have this issue.

Dmitry Fleytman (1):
  RX initialization sequence fixed - enable RX after corresponding ring
    initialization only
