Subject: [PULL 21/33] net: cadence_gem: TX_LAST bit should be set by guest
Date: Tue, 16 Jun 2020 14:45:32 +0800	[thread overview]
Message-ID: <1592289944-13727-22-git-send-email-jasowang@redhat.com> (raw)
In-Reply-To: <1592289944-13727-1-git-send-email-jasowang@redhat.com>

From: Sai Pavan Boddu <sai.pavan.boddu@xilinx.com>

TX_LAST bit should not be set by hardware, its set by guest to inform
the last bd of the frame.
