From: Karun Eagalapati <[email protected]> BUFFER_AVAILABLE interrupt is sent by firmware to indicate change in buffer status. We should check buffer status while handling this interrupt. Currently buffer status is checked only while dequeueing packets. This patch fixes a data traffic stuck problem observed occasionally.
