selftests: forwarding: Add test for minimum and maximum MTU
Add cases to check minimum and maximum MTU which are exposed via "ip -d link show". Test configuration and traffic. Use VLAN devices as usually VLAN header (4 bytes) is not included in the MTU, and drivers should configure hardware correctly to send maximum MTU payload size in VLAN tagged packets. $ ./min_max_mtu.sh TEST: ping [ OK ] TEST: ping6 [ OK ] TEST: Test maximum MTU configuration [ OK ] TEST: Test traffic, packet size is maximum MTU [ OK ] TEST: Test minimum MTU configuration [ OK ] TEST: Test traffic, packet size is minimum MTU [ OK ] Signed-off-by: Amit Cohen <amcohen@nvidia.com> Reviewed-by: Petr Machata <petrm@nvidia.com> Signed-off-by: Petr Machata <petrm@nvidia.com> Link: https://lore.kernel.org/r/89de8be8989db7a97f3b39e3c9da695673e78d2e.1718275854.git.petrm@nvidia.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
