Infiniband clients must be attached and detached in a specific order in ibcore. Currently the linking order of the infiniband, IB, modules decide in which order the clients are attached and detached. For example one IB client may use resources from another IB client. This can lead to a potential deadlock at shutdown. For example if the ipoib is unregistered after the ib_multicast client is detached, then if ipoib is using multicast addresses a deadlock may happen, because ib_multicast will wait for all its resources to be freed before returning from the remove method. Fix this by using module_xxx_order() instead of module_xxx(). Differential Revision: https://reviews.freebsd.org/D23973 Sponsored by: Mellanox Technologies

Improve support for switching to and from command polling mode in mlx4core. Make sure the enter and leave polling routines can be called multiple times with same setting. Ignore setting polling or event mode twice. This fixes a deadlock during shutdown if polling mode was already selected. Sponsored by: Mellanox Technologies

Teardown ifnet after stopping port in the mlx4en(4) driver. mlx4_en_stop_port() calls mlx4_en_put_qp() which can refer the link level address of the network interface, which in turn will be freed by the network interface detach function. Make sure the port is stopped before detaching the network interface. Sponsored by: Mellanox Technologies
