Revision 21f1b8a6636c4dbde4aa1ec0343f42eaf653ffcc authored by Paolo Abeni on 26 April 2019, 10:50:44 UTC, committed by David S. Miller on 28 April 2019, 02:07:24 UTC
Currently, the UDP GRO code path does bad things on some edge conditions - Aggregation can happen even on packet with different lengths. Fix the above by rewriting the 'complete' condition for GRO packets. While at it, note explicitly that we allow merging the first packet per burst below gso_size.
