Date: Tue, 17 Aug 2021 11:27:24 +0200 From: Magnus Karlsson <magnus.karlsson@...il.com> To: magnus.karlsson@...el.com, bjorn@...nel.org, ast@...nel.org, daniel@...earbox.net, netdev@...r.kernel.org, maciej.fijalkowski@...el.com Cc: jonathan.lemon@...il.com, ciara.loftus@...el.com, bpf@...r.kernel.org, yhs@...com, andrii@...nel.org Subject: [PATCH bpf-next v2 11/16] selftests: xsk: decrease batch size From: Magnus Karlsson <magnus.karlsson@...el.com> Decrease the batch size from 64 to 8 to avoid potentially overflowing some buffers in the skb case that leads to dropped packets we cannot control (and thus the tests may generate false negatives).
