Subject: [PATCH net] drivers/net/wan/lapbether: Added needed_tailroom
Date: Sat,  8 Aug 2020 10:52:51 -0700	[thread overview]
Message-ID: <20200808175251.582781-1-xie.he.0141@gmail.com> (raw)

The underlying Ethernet device may request necessary tailroom to be
allocated by setting needed_tailroom. This driver should also set
needed_tailroom to request the tailroom needed by the underlying
Ethernet device to be allocated.
