From bef05406ac0ea6f468e1e25e9934f3011ea9259b Mon Sep 17 00:00:00 2001 From: Dmitry Kravkov Date: Tue, 11 Sep 2012 04:34:08 +0000 Subject: bnx2x: Avoid sending multiple statistics queries During traffic when DCB is enabled, it is possible for multiple instances of statistics queries to be sent to the chip - this may cause the FW to assert. This patch prevents the sending of an additional instance of statistics query while the previous query hasn't completed.
