Is there any more information that can be provided (or tests done) to assist
in tracking this problem down?  Based on the tests done in December it seems
that the problem only affects specific RTL-8169 variants, with most being
ok.  Is it a case that we simply need to accept that for the greater good
commit da78dbff2e05630921c551dbbc70a4b7981a8fff has permanently broken
Netgear GA311 [1] network cards with respect to these UDP packets and that
nothing can be done?

For future reference, commit 6b839b6cf9eada30b086effb51e5d6076bafc761
("r8169: fix NAPI handling under high load") appears to have fixed the
regression documented by this thread.  Thanks to Heiner Kallweit for the
work which lead to this solution.
