From 8c99e7b0436473593a68e740d1032909bc5335a1 Mon Sep 17 00:00:00 2001 From: Yaniv Rosner Date: Wed, 13 Aug 2008 15:56:17 -0700 Subject: [PATCH] bnx2x: Pause settings Pause settings - 1G pause was not working due to missing write to the emac block (TX_MODE_FLOW_EN) - The flow control should use the negotiated result (after autoneg) so we should save both the requested autoneg and the result - The HW credits with flow control at 1G speed were not optimized and caused low throughput - It is recommended to turn off flow control if the MTU is bigger than 5000B due to internal buffers size Signed-off-by: Yaniv Rosner Signed-off-by: Eilon Greenstein Signed-off-by: David S.
