Subject: [PATCH v3 09/13] hw/net: ne2000: Remove the logic of padding short frames in the receive path
Date: Tue, 16 Mar 2021 16:12:50 +0800 [thread overview]
Message-ID: <20210316081254.72684-10-bmeng.cn@gmail.com> (raw)
In-Reply-To: <20210316081254.72684-1-bmeng.cn@gmail.com>
Now that we have implemented unified short frames padding in the
QEMU networking codes, remove the same logic in the NIC codes.
