From 67c52a4dafceca8ed63b2d8dc73079059e064399 Mon Sep 17 00:00:00 2001 From: Karun Eagalapati Date: Thu, 3 Aug 2017 19:59:03 +0530 Subject: [PATCH] rsi: buffer available interrupt handling 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.
