Subject: [PATCH bpf-next 12/17] selftests: xsk: decrease batch size
Date: Tue, 27 Jul 2021 15:17:48 +0200	[thread overview]
Message-ID: <20210727131753.10924-13-magnus.karlsson@gmail.com> (raw)
In-Reply-To: <20210727131753.10924-1-magnus.karlsson@gmail.com>

From: Magnus Karlsson <magnus.karlsson@intel.com>

Decrease the batch size from 64 to 8 to stress the system some more
and avoid potentially overflowing some buffers in the skb case.
