I see.  Should I assume therefore that a permanent fix *might* get into the
kernel someday, but that there is no timeframe and no guarantee?

I should mention that while I currently have access to hardware to test for
the problem, this may not be the case in a few months time since the
hardware (the computer and network devices) is slated for deployment.

Thank you for helping me to understand what the situation is regarding
intentions for mainline.

While we have seen the current issue on GA311 cards (and this is what is
currently in our test setup), it's also been observed with other r8169-based
cards (a D-Link from memory).
