Introduce bpf_sol_tcp_getsockopt() helper.
Add bpf_getsockopt for RTO MIN and DELACK MAX.
Add corresponding selftests for bpf.

v3
Link: https://lore.kernel.org/all/20250311085437.14703-1-kernel...
1. Remove 2 bpf unrelated patches which will be separately submitted
after the netdev conference. So this series is consist of pure BPF
modification.
2. Fix selftests by adjusting the test/expected value because some arch
configs use HZ=100. Now those two selftests can be used from HZ=100 to
HZ=1000.
v2
Link: https://lore.kernel.org/all/20250309123004.85612-1-kernel...
1. add bpf getsockopt common helper
2. target bpf-next net branch
Jason Xing (4):
tcp: bpf: introduce bpf_sol_tcp_getsockopt to support TCP_BPF flags
tcp: bpf: support bpf_getsockopt for TCP_BPF_RTO_MIN
tcp: bpf: support bpf_getsockopt for TCP_BPF_DELACK_MAX
selftests: add bpf_set/getsockopt() for TCP_BPF_DELACK_MAX and
TCP_BPF_RTO_MIN
