From 60240bc26114543fcbfcd8a28466e67e77b20388 Mon Sep 17 00:00:00 2001 From: Jalal Mostafa Date: Wed, 21 Sep 2022 13:57:01 +0000 Subject: xsk: Inherit need_wakeup flag for shared sockets The flag for need_wakeup is not set for xsks with `XDP_SHARED_UMEM` flag and of different queue ids and/or devices. They should inherit the flag from the first socket buffer pool since no flags can be specified once `XDP_SHARED_UMEM` is specified.
