Merge branch 'selftests-drv-net-fix-and-improve-command-requirement-checking'

Gal Pressman says:

====================
selftests: drv-net: Fix and improve command requirement checking

This series fixes remote command checking and cleans up command
requirement calls across tests.

The first patch fixes require_cmd() incorrectly checking commands
locally even when remote=True was specified due to a missing host
parameter.

The second patch makes require_cmd() usage explicit about local/remote
requirements, avoiding unnecessary test failures and consolidating
duplicate calls.
