From 9e25dd9d65d27aa94220831fe6453d935988801c Mon Sep 17 00:00:00 2001 From: Alexander Lobakin Date: Tue, 3 Dec 2024 18:37:28 +0100 Subject: [PATCH] xsk: allow attaching XSk pool via xdp_rxq_info_reg_mem_model() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When you register an XSk pool as XDP Rxq info memory model, you then need to manually attach it after the registration. Let the user combine both actions into one by just passing a pointer to the pool directly to xdp_rxq_info_reg_mem_model(), which will take care of calling xsk_pool_set_rxq_info(). This looks similar to how a &page_pool gets registered and reduce repeating driver code.
