From f8ebfaf6684b03084858d8c55f81867e5171af08 Mon Sep 17 00:00:00 2001 From: Jan Sokolowski Date: Wed, 13 Feb 2019 18:07:29 +0100 Subject: net: bpf: remove XDP_QUERY_XSK_UMEM enumerator MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit c9b47cc1fabc ("xsk: fix bug when trying to use both copy and zero-copy on one queue id") moved the umem query code to the AF_XDP core, and therefore removed the need to query the netdevice for a umem. This patch removes XDP_QUERY_XSK_UMEM and all code that implement that behavior, which is just dead code.
