Subject: [PATCH net-next] net: rmnet: set NETIF_F_LLTX flag
Date: Sun, 8 Mar 2020 13:47:06 +0000 [thread overview]
Message-ID: <20200308134706.18727-1-ap420073@gmail.com> (raw)
The rmnet_vnd_setup(), which is the callback of ->ndo_start_xmit() is
allowed to call concurrently because it uses RCU protected data.
So, it doesn't need tx lock.
