[PATCH bpf-next v2 2/2] selftests/bpf: Add IP_TRANSPARENT and IPV6_TRANSPARENT to setget_sockopt
From: Shivaji Kant
Date: Sat Aug 01 2026 - 01:15:25 EST
Add test coverage for IP_TRANSPARENT and IPV6_TRANSPARENT socket options
in the setget_sockopt BPF selftest to verify bpf_setsockopt() and
bpf_getsockopt() helpers.
