2018-12-20IB/usnic: Fix potential deadlockParvi Kaustubhi1-4/+7
Acquiring the rtnl lock while holding usdev_lock could result in a deadlock. For example: usnic_ib_query_port() | mutex_lock(&us_ibdev->usdev_lock) | ib_get_eth_speed() | rtnl_lock() rtnl_lock() | usnic_ib_netdevice_event() | mutex_lock(&us_ibdev->usdev_lock) This commit moves the usdev_lock acquisition after the rtnl lock has been released. This is safe to do because usdev_lock is not protecting anything being accessed in ib_get_eth_speed(). Hence, the correct order of holding locks (rtnl -> usdev_lock) is not violated.

With the introduction of SR-IOV LAG, checking whether LAG is active is no longer good enough, since RoCE and SR-IOV LAG each entails different behavior by both the core and infiniband drivers.

2018-12-14IB/mlx5: Unify e-switch representors load approach between uplink and VFsMark Bloch3-22/+19
When in switchdev mode and the add function is called by the core level driver, make sure we only register the callbacks, but don't create the mlx5 IB device or initialize anything. With this change all the IB devices in switchdev mode are created only once the load callback is invoked by the e-switch core sub-module. This follows the design paradigm under which the all the Eth representors must be loaded before any of IB reprs is loaded.
