Thanks for your work on this feature. I don't have hardware to test
it. Just some comments on the code.

This looks duplicated. The last line shouldn't be there?

If I understand it correctly, this shell command is executed 50 times
per second. Wouldn't it be sufficient to specify it as a file to be
read directly instead instead of calling popen()?
I assume this is a temporary solution until the kernel provides a
standard ethtool/netlink API for monitoring and configuring SyncE.
