selftests/tc-testing: Add selftests for qdisc DualPI2
Update configuration of tc-tests and preload DualPI2 module for self-tests, and add following self-test cases for DualPI2: Test a4c7: Create DualPI2 with default setting Test 1ea4: Create DualPI2 with memlimit Test 2130: Create DualPI2 with typical_rtt and max_rtt Test 90c1: Create DualPI2 with max_rtt Test 7b3c: Create DualPI2 with any_ect option Test 49a3: Create DualPI2 with overflow option Test d0a1: Create DualPI2 with drop_enqueue option Test f051: Create DualPI2 with no_split_gso option Test 456b: Create DualPI2 with packet step_thresh Test 610c: Create DualPI2 with packet min_qlen_step Test b4fa: Create DualPI2 with packet coupling_factor Test 37f1: Create DualPI2 with packet classic_protection Signed-off-by: Chia-Yu Chang <chia-yu.chang@nokia-bell-labs.com> Reviewed-by: Victor Nogueira <victor@mojatatu.com> Link: https://patch.msgid.link/20250722095915.24485-6-chia-yu.chang@nokia-bell-labs.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
