Subject: [PATCH net v2 0/2] net: netem: fix further issues with packet corruption

Hi!

This set is fixing two more issues with the netem packet corruption.

First patch (which was previously posted) avoids NULL pointer dereference
if the first frame gets freed due to allocation or checksum failure.
v2 improves the clarity of the code a little as requested by Cong.

Second patch ensures we don't return SUCCESS if the frame was in fact
dropped. Thanks to this commit message for patch 1 no longer needs the
"this will still break with a single-frame failure" disclaimer.

Jakub Kicinski (2):
  net: netem: fix error path for corrupted GSO frames
  net: netem: correct the parent's backlog when corrupted packet was
    dropped
