Subject: [PATCH v3 0/2] selftests/rdma: Add an eBPF-based testcase using netkit for RXE
Date: Wed, 21 Oct 2026 13:31:13 -0700 [thread overview]
Message-ID: <20261021203115.54560-1-yanjun.zhu@linux.dev> (raw)
Add a new self-test case to verify RXE (Soft-RoCE) traffic using
netkit virtual interfaces and an eBPF tcx ingress program to dump
and parse RDMA transport headers (BTH, etc.).
The test results:
