Fix the following coccicheck warning: tools/testing/selftests/net/udpgso_bench_tx.c:297:18-19: WARNING opportunity for min() tools/testing/selftests/net/udpgso_bench_tx.c:354:27-28: WARNING opportunity for min() tools/testing/selftests/net/so_txtime.c:129:24-26: WARNING opportunity for max() tools/testing/selftests/net/so_txtime.c:96:30-31: WARNING opportunity for max()

Signed-off-by: Mahmoud Maatuq mahmoudmatook.mm@gmail.com --- changes in v3: remove Suggested-by tag fix wrong comment inside selftests/net/Makefile

changes in v2: cast var cfg_mss to int to avoid static assertion after providing a stricter version of min() that does signedness checking. --- tools/testing/selftests/net/Makefile | 2 ++ tools/testing/selftests/net/so_txtime.c | 7 ++++--- tools/testing/selftests/net/udpgso_bench_tx.c | 6 +++--- 3 files changed, 9 insertions(+), 6 deletions(-)
