2020-01-13net: macb: fix for fixed-link modeMilind Parab
This patch fix the issue with fixed link. With fixed-link device opening fails due to macb_phylink_connect not handling fixed-link mode, in which case no MAC-PHY connection is needed and phylink_connect return success (0), however in current driver attempt is made to search and connect to PHY even for fixed-link.

Add a new test for TBS feature which is used in ETF scheduler. In this test, we send a packet with a launch time specified as now + 500ms and check if the packet was transmitted on that time frame.

In order to probe this ethernet interface from the device tree all physical MMIO regions must be passed as resources.

2020-01-12net: ethernet: ixp4xx: Standard module initLinus Walleij
The IXP4xx driver was initializing the MDIO bus before even probing, in the callbacks supposed to be used for setting up the module itself, and with the side effect of trying to register the MDIO bus as soon as this module was loaded or compiled into the kernel whether the device was discovered or not. This does not work with multiplatform environments. To get rid of this: set up the MDIO bus from the probe() callback and remove it in the remove() callback. Rename the probe() and remove() calls to reflect the most common conventions. Since there is a bit of checking for the ethernet feature to be present in the MDIO registering function, making the whole module not even be registered if we can't find an MDIO bus, we need something similar: register the MDIO bus when the corresponding ethernet is probed, and return -EPROBE_DEFER on the other interfaces until this happens. If no MDIO bus is present on any of the registered interfaces we will eventually bail out. None of the platforms I've seen has e.g. MDIO on EthB and only uses EthC, there is always a Ethernet hardware on the NPE (B, C) that has the MDIO bus, we just might have to wait for it.

2020-01-11net: hns3: refactor the notification scheme of PF resetHuazhong Tan
hclge_reset_prepare_down() is only used to inform VF that PF is going to do function reset, then using hclge_func_reset_sync_vf() in hclge_reset_prepare_wait() to query whether VF is ready before asserting PF function reset. To make the code more readable, this patch uses a new function hclge_function_reset_notify_vf() to do this job. Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: David S.

2020-01-11net: hns3: modify hclge_func_reset_sync_vf()'s return type to voidHuazhong Tan
When synchronizes with VFs fail before PF function reset, PF driver should go on its function reset, otherwise it can not run normally anymore. So, hclge_func_reset_sync_vf() should not affect the processing of PF reset, this patch modifies its return type to void. Signed-off-by: Huazhong Tan <tanhuazhong@huawei.com> Signed-off-by: David S.

2020-01-11net: hns3: enlarge HCLGE_RESET_WAIT_CNTHuazhong Tan

2020-01-11net: hns3: refactor the procedure of VF FLRHuazhong Tan
Currently, the actual work of VF FLR is handled in the reset task, which is asynchronous. So in some case, if the preparing and rebuilding are not done, then the VF FLR will trigger some problems, for example, makes hardware go into chaos. So this patch separates the process of VF FLR from reset task, and adds a semaphore to serialize this reset and others. When FLR's preparing fails, if there has other higher level reset pending or failing times less than the HCLGE_FLR_RETRY_CNT, this preparing should be retried, otherwise it will get into a wrong state. BTW, while the hardware reports misc interrupt during pcie_flr(), the driver can not receive this interrupt anymore, so disable it when hclgevf_flr_prepare() return, and re-enable it when enter hclgevf_flr_done(). Avoid declaring internal function hclgevf_enable_vector(), this patch also moves its definition forward, and removes unused enum hnae3_flr_state.

hclgevf_reset() is a little bloated, and the process of VF FLR will be separated from the reset task later. So this patch splits hclgevf_reset() into hclgevf_reset_prepare() and hclge_reset_rebuild(), then FLR can also reuse these two functions. Also moves HNAE3_UP_CLIENT into hclgevf_reset_stack().
