Only call rtl8169_xmit_frags() if the skb is actually fragmented. This avoid a small overhead for non-fragmented skb's, and it allows to simplify rtl8169_xmit_frags() a little. Signed-off-by:

The non-zero check on rc is redundant as a previous non-zero check on rc will always return and the second check is never reached, hence it is redundant and can be removed. Also remove a blank line. Addresses-Coverity: ("Logically dead code") Signed-off-by: -

Since commit f3a52c61 ("mlxsw: pci: Utilize MRSR register to perform FW reset") the driver no longer issues a reset via the PCI BAR, so the offset of the reset bit is unused. Remove it. Signed-off-by:

During packet receive, only the first matching RX listener in rx_listener_list is going to get the packet. So there is no meaning in registering two equal listeners with different privs. Remove priv from equality comparison and disable possibility of doing it. Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Remove RTNL from route insertion path This patch set removes RTNL from the route insertion path in mlxsw in order to reduce the control plane latency: the time it takes to push routes from user space to the kernel and mlxsw. Up until now mlxsw did not have a lock to protect its shared router data structures and instead relied on RTNL. While this was simple and worked, it resulted in large control plane latencies as RTNL was heavily contended - by both the task receiving the netlink messages from user space and the mlxsw workqueue that programs the routes to the device. By removing RTNL and introducing a new router mutex, this patch set reduces the control plane latency by ~80%. A single mutex is added as inside mlxsw there is not a lot of concurrency. In addition, a more fine-grained locking scheme is much more error-prone. Patches #1-#6 are preparations. They add needed locking in NVE and multicast routing code instead of relying on RTNL Patch #7 introduces the new mutex Patches #8-#12 gradually take the lock in various entry points into the routing code Patch #13 removes RTNL in places where it is no longer required ==================== Signed-off-by: -

After introducing the router lock in previous patches and making sure it protects internal router structures, we no longer need to rely on RTNL to serialize access to these structures. Remove RTNL from call sites that no longer require it. Two calls sites that keep taking the lock are mlxsw_sp_router_fibmr_event_work() and mlxsw_sp_inet6addr_event_work(). The first calls into ACL code that still assumes RTNL is taken. The second potentially calls into the FID code that also relies on RTNL. Removing RTNL from these two call sites is the subject of future work. Signed-off-by:

The routing code exports some helper functions that can be called from other driver modules such as the bridge. These helpers are never called with the router lock already held and therefore need to take it in order to serialize access to shared router structures. Signed-off-by:

Another entry point into the routing code is from inetaddr listeners. The driver registers listeners to IPv4 and IPv6 inetaddr notification chains in order to understand when a RIF needs to be created or destroyed. Serialize access to shared router structures from these listeners by taking the router lock when processing inetaddr events. Signed-off-by:

One entry point into the routing code is from the netdev listener block. Some netdev events require access to internal router structures. For example, changing the MTU of a netdev requires looking-up the backing RIF and adjusting its MTU. In order to serialize access to shared router structures, take the router lock when processing netdev events that require access to it. Signed-off-by:

The dpipe code traverses internal router structures such as neighbours and adjacency entries and dumps them to user space via netlink. Up until now the routing code did not have its own locks and relied on RTNL lock to serialize access. This is going to change with the introduction of the router lock. Take the router lock in the code paths where RTNL lock is currently taken so that the latter could be removed by subsequent patches. Signed-off-by:
