selftests: net: give more time for GRO aggregation
[ Upstream commit 89abe628375301fedb68770644df845d49018d8b ]
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.
