Here is my (quick and dirty) patch which makes the link detection working and adds the traces shown above : diff --git a/drivers/net/ethernet/broadcom/bnx2x/bnx2x_cmn.c b/drivers/net/ethernet/broadcom/bnx2x/bnx2x_cmn.c index 580b44e..dedd810 100644 --- a/drivers/net/ethernet/broadcom/bnx2x/bnx2x_cmn.c +++ b/drivers/net/ethernet/broadcom/bnx2x/bnx2x_cmn.c @@ -1769,6 +1769,7 @@ int bnx2x_nic_load(struct bnx2x *bp, int load_mode) */ if (!BP_NOMCP(bp)) { load_code = bnx2x_fw_command(bp, DRV_MSG_CODE_LOAD_REQ, 0); +netdev_info(bp->dev, "bnx2x_nic_load bnx2x_fw_command load_code=0x%08X\n",load_code); if (!load_code) { BNX2X_ERR("MCP response failure, aborting\n"); rc = -EBUSY; @@ -1785,22 +1786,31 @@ int bnx2x_nic_load(struct bnx2x *bp, int load_mode) DP(NETIF_MSG_IFUP, "NO MCP - load counts[%d] %d, %d, %d\n", path, load_count[path][0], load_count[path][1], load_count[path][2]); +netdev_info(bp->dev, "bnx2x_nic_load NO MCP - load counts[%d] %d, %d, %d\n", + path, load_count[path][0], load_count[path][1], + load_count[path][2]); load_count[path][0]++; load_count[path][1 + port]++; DP(NETIF_MSG_IFUP, "NO MCP - new load counts[%d] %d, %d, %d\n", path, load_count[path][0], load_count[path][1], load_count[path][2]); +netdev_info(bp->dev, "bnx2x_nic_load NO MCP - new load counts[%d] %d, %d, %d\n", + path, load_count[path][0], load_count[path][1], + load_count[path][2]); if (load_count[path][0] == 1) load_code = FW_MSG_CODE_DRV_LOAD_COMMON; else if (load_count[path][1 + port] == 1) load_code = FW_MSG_CODE_DRV_LOAD_PORT; else load_code = FW_MSG_CODE_DRV_LOAD_FUNCTION; +netdev_info(bp->dev, "bnx2x_nic_load autre load_code=0x%08X\n",load_code); } +netdev_info(bp->dev, "bnx2x_nic_load load_code=0x%08X\n",load_code); if ((load_code == FW_MSG_CODE_DRV_LOAD_COMMON) || (load_code == FW_MSG_CODE_DRV_LOAD_COMMON_CHIP) || - (load_code == FW_MSG_CODE_DRV_LOAD_PORT)) { + (load_code == FW_MSG_CODE_DRV_LOAD_PORT) || + (load_code == FW_MSG_CODE_DRV_LOAD_FUNCTION)) { bp->port.pmf = 1; /* * We need the barrier to ensure the ordering between the @@ -1808,9 +1818,13 @@ int bnx2x_nic_load(struct bnx2x *bp, int load_mode) * bnx2x_periodic_task(). */ smp_mb(); +netdev_info(bp->dev, "bnx2x_nic_load start period\n"); queue_delayed_work(bnx2x_wq, &bp->period_task, 0); } else +{ +netdev_info(bp->dev, "bnx2x_nic_load NOT start period\n"); bp->port.pmf = 0; +} DP(NETIF_MSG_LINK, "pmf %d\n", bp->port.pmf); Hope it can help...
