Commit 2abb7cdc ("udp: Add support for doing checksum unnecessary conversion") caused napi_gro_cb structs with the "flush" field zero to take the "udp_gro_receive" path rather than the "set flush to 1" path that they would previously take. As a result I saw booting from an NFS root hang shortly after starting userspace, with "server not responding" messages. This change to the handling of "flush == 0" packets appears to be incidental to the goal of adding new code in the case where skb_gro_checksum_validate_zero_check() returns zero. Based on that and the fact that it breaks things, I'm assuming that it is unintentional.
