The GRO selftests can flake and have some confusing behavior. These
changes make the output and return value of GRO behave as expected, then
deflake the tests.

v2:
- Split into multiple commits.
- Reduced napi_defer_hard_irqs to 1.
- Reduced gro_flush_timeout to 100us.
- Fixed comment that wasn't updated.

v1: https://lore.kernel.org/netdev/20250218164555.1955400-1-krakauer@google.com/

Kevin Krakauer (3):
  selftests/net: have `gro.sh -t` return a correct exit code
  selftests/net: only print passing message in GRO tests when tests pass
  selftests/net: deflake GRO tests
