selftests: drv-net: Make command requirements explicit

2025-07-25T01:52:00+00:00

Make require_cmd() calls explicit about whether commands are needed locally, remotely, or both. Since require_cmd() defaults to local=True, tests should explicitly set local=False when commands are only needed remotely. - socat: Set local=False since it's only needed on remote hosts. - iperf3: Use single call with both local=True and remote=True since it's needed on both hosts. This avoids unnecessary test failures when commands are missing locally but available remotely where actually needed, and consolidates a duplicate require_cmd() call into single call that checks both hosts.

selftests: drv: net: add version indicator

selftests: drv: net: avoid skipping tests

2025-05-06T01:17:16+00:00

On a system with either of the ipv4 or ipv6 information missing, tests are currently skipped. Ideally, the test should run as long as at least one address family is present. This patch make test run whenever possible.

selftests: drv: net: fix test failure on ipv6 sys

2025-05-06T01:17:15+00:00

The `get_interface_info` call has ip version hard-coded which leads to failures on an IPV6 system. The NetDrvEnv class already gathers information about remote interface, so instead of fixing the local implementation switch to using cfg.remote_ifname.

selftests: drv-net: fix merge conflicts resolution

2025-03-14T09:24:14+00:00

After the recent merge between net-next and net, I got some conflicts on my side because the merge resolution was different from Stephen's one [1] I applied on my side in the MPTCP tree. It looks like the code that is now in net-next is using the old way to retrieve the local and remote addresses. This patch is now using the new way, like what was in Stephen's email [1]. Also, in get_interface_info(), there were no conflicts in this area, because that was new code from 'net', but a small adaptation was needed there as well to get the remote address.
