Message-Id: <1430761396-4878-1-git-send-email-nathan.sullivan@ni.com> Date: Mon, 4 May 2015 12:43:15 -0500 From: Nathan Sullivan <nathan.sullivan@...com> To: netdev@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Nathan Sullivan <nathan.sullivan@...com> Subject: [PATCH] net: macb: Do not enable RX buffer used interrupt This driver does not handle the RX buffer used interrupt, nor does it need to due to handling the RX overflow interrupt already. Enabling the interrupt would lead to an infinite loop in the ISR.
