(cherry picked from commit d64ec841517a25f6d468bde9f67e5b4cffdc67c7)

Resolve conflicts as follows:

In the original CL, changes are made to many chip-specific configuration
functions, such as rtl_hw_start_8168e_2, rtl_hw_start_8402, etc. Our
source is missing some of these configuration functions and others do
not integrate cleanly. Therefore, only apply the changes to the hw_start
functions that integrate cleanly:

rtl_hw_start_8168e_2
rtl_hw_start_8105e_1

TEST=Confirm basic functionality on 8168e and 8105e cards.
