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 
udp: fix GRO reception in case of length mismatch
 
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.
