Subject: [PATCH] dpaa_eth: NETIF_F_LLTX requires to do our own update of trans_start
Date: Thu, 17 Jan 2019 11:42:27 +0200 [thread overview]
Message-ID: <1547718147-5040-1-git-send-email-madalin.bucur@nxp.com> (raw)
As txq_trans_update() only updates trans_start when the lock is held,
trans_start does not get updated if NETIF_F_LLTX is declared.
