Hi all,

I am a CS professor (and first time contributor) and have been using
qemu in my courses for over a decade, especially a course that asks
students to write major pieces of an OS kernel from starter code.

I have some patches, originally from Austin Clements at MIT, that I
have found useful over the years and that may be useful to others.  It
would also be nice not to have to build a custom qemu each semester.  I
have cleared upstreaming these with Austin, the original author.

In order to learn the process and community, I thought I would start
with one patch.  As the description says, it enables e1000 debugging
without recompilation.  One project in the course is to write an e1000
driver, and these logs are quite helpful to students.

Thank you in advance for your time,
Don Porter
