This series addresses a regression in ethtool flow steering where rules targeting the default RSS context (context 0) were incorrectly rejected.
The default RSS context always exists but is not stored in the rss_ctx xarray like additional contexts. The current validation logic was checking for the existence of context 0 in this array, causing valid flow steering rules to be rejected. This prevented configurations such as: - High priority rules directing specific traffic to the default context - Low priority catch-all rules directing remaining traffic to additional contexts Patch 1 fixes the validation logic to skip the existence check for context 0. Patch 2 adds a selftest that verifies this behavior.
