Avoid a VLA[1] by using a real constant expression instead of a variable. The compiler should be able to optimize the original code and avoid using an actual VLA. Anyway this change is useful because it will avoid a false positive with -Wvla, it might also help the compiler generating better code. [1] https://lkml.org/lkml/2018/3/7/621Signed-off-by:

Function lan743x_phy_init assigns pointer 'netdev' but this is never read and hence it can be removed. The return error code handling can also be cleaned up to remove the variable 'ret'. Function lan743x_phy_link_status_change assigns pointer 'phy' twice and this is never read, so it also can be removed. Finally, function lan743x_tx_napi_poll initializes pointer 'adapter' and then re-assigns the same value into this pointer a little later on so this second assignment is redundant and can be also removed.

Ido Schimmel says: ==================== mlxsw: Removing dependency of mlxsw on GRE Petr says: mlxsw_spectrum supports offloading of a tc action mirred egress mirror to a gretap or ip6gretap netdevice, which necessitates calls to functions defined in ip_gre, ip6_gre and ip6_tunnel modules. Previously this was enabled by introducing a hard dependency of MLXSW_SPECTRUM on NET_IPGRE and IPV6_GRE. However the rest of mlxsw is careful about picking which modules are absolutely required, and therefore the better approach is to make mlxsw_spectrum tolerant of absence of one or both of the GRE flavors. One way this might be resolved is by keeping the code in mlxsw_spectrum intact, and defining defaults for functions that mlxsw_spectrum depends on. The downsides are that other modules end up littered with these do-nothing defaults; that the driver ends up carrying quite a bit of dead code; and that the driver ends up having to explicitly depend on IPV6_TUNNEL to prevent configurations where mlxsw_spectrum is compiled in and and ip6_tunnel is a module, something that it currently can treat as an implementation detail of the IPV6_GRE dependency. Alternatively, the driver should just bite the bullet and ifdef-out the code that handles configurations that are not supported. Since that's what we are doing for IPv6 dependency, let's do the same for the GRE flavors. Patch #1 introduces a wrapper function for determining the value of ipv6.sysctl.multipath_hash_policy, which defaults to 0 on non-IPv6 builds. That function is then used from spectrum_router.c, instead of the direct variable reference that was introduced there during the short window when the Spectrum driver had a hard dependency on IPv6. Patch #2 moves one function to keep together in one block all the callbacks for handling (IPv4) gretap mirroring. Patch #3 then introduces the ifdefs to hide the irrelevant code. ==================== Signed-off-by: -

Hence rework the NET_IPGRE and IPV6_GRE dependencies to just guard matching modularity, and hide the corresponding code in spectrum_span.c in an #if IS_ENABLED. Mark mlxsw_sp_span_entry_tunnel_parms_common as maybe unused, to muffle warnings if neither GRE flavor is selected, which seems cleaner than introducing a composite #if. Signed-off-by:

In order to abstract away access to the ipv6.sysctl.multipath_hash_policy variable, which is not available on systems compiled without IPv6 support, introduce a wrapper function ip6_multipath_hash_policy() that falls back to 0 on non-IPv6 systems. Use this wrapper from mlxsw/spectrum_router instead of a direct reference. Signed-off-by:

In a scenario where the command queued to firmware get dropped or times out, MTU change from host will not propagate to firmware. So, it is required for host driver to wait for response from firmware or timeout and then return correct status to caller of ndo_change_mtu.

VF changes unicast mac address by sending mailbox msg to PF, then PF completes the mac address modification. It may fail when the target uc mac address is already in the mac_vlan table. VF should be aware of it by reading the message result. Signed-off-by:

It's not allowed to add two same unicast mac address entries to the mac_vlan table. When modify the uc mac address of a VF device to the same value with the PF device's, the PF device will lose its entry of the mac_vlan table. Lookup the mac address in the mac_vlan table, and add it if the entry is inexistent. Fixes: 46a3df9f ("net: hns3: Add HNS3 Acceleration Engine & Compatibility Layer Support") Signed-off-by:

Error code -EIO was used to indicate mutilple errors in function hclge_get_mac_vlan_cmd_status().This patch fixes it by using error code depending on the error type. For no space error, return -ENOSPC. For entry not found, return -ENOENT. For command send fail, return -EIO. For invalid op code, return -EINVAL.

The link status update function is called by timer every second. But net_stop and net_open may be called with very short intervals. The link status update function can not detect the link state has changed. It causes the netdev not running problem. This patch fixes it by updating the link state in ae_stop function. Signed-off-by:

Some users want to be able to run the tests without a configuration file which is useful when one needs to test both virtual and physical interfaces on the same machine.

Using up 8 bytes in every ipaddr object to store SETIP/DELIP flags is rather wasteful. Except for takeover eligibility, the flag values all just depend on the address type, so determine them on demand. While at it reorder the struct to fill an alignment hole. Signed-off-by:

Extract a helper that does the actual work & returns the right NOTIFY_* responses, and start putting the temporary ipaddr container objects on the stack rather than kmalloc'ing them.

init_qdio_queues() resets the Input Queue's overall QDIO state, and positions the buffer cursor back to 0. So this is the obvious place to also reset the queue's NAPI context (in contrast to doing it rather randomly in the middle of the big set_online() path). No functional change. Signed-off-by:
