From a166ab7816c534973745b0fe7bce3c8cefc5426f Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Thu, 17 Jul 2025 16:43:41 -0700 Subject: ethtool: rss: support creating contexts via Netlink Support creating contexts via Netlink. Setting flow hashing fields on the new context is not supported at this stage, it can be added later. An empty indirection table is not supported. This is a carry over from the IOCTL interface where empty indirection table meant delete. We can repurpose empty indirection table in Netlink but for now to avoid confusion reject it using the policy. Support letting user choose the ID for the new context. This was not possible in IOCTL since the context ID field for the create action had to be set to the ETH_RXFH_CONTEXT_ALLOC magic value.
