The gro.sh test-case relay on the gro_flush_timeout to ensure that all the segments belonging to any given batch are properly aggregated.

The other end, the sender is a user-space program transmitting each packet with a separate write syscall. A busy host and/or stracing the sender program can make the relevant segments reach the GRO engine after the flush timeout triggers.

Give the GRO flush timeout more slack, to avoid sporadic self-tests failures.
