Subject: [PATCH v3 02/13] net: Add a 'do_not_pad" to NetClientState
Date: Tue, 16 Mar 2021 16:12:43 +0800	[thread overview]
Message-ID: <20210316081254.72684-3-bmeng.cn@gmail.com> (raw)
In-Reply-To: <20210316081254.72684-1-bmeng.cn@gmail.com>

This adds a flag in NetClientState, so that a net client can tell
its peer that the packets do not need to be padded to the minimum
size of an Ethernet frame (60 bytes) before sending to it.
