IB/IPoIB: Separate control from HW operation on ipoib_open/stop ndo
This patch is preparing the netdev part at the IPoIB driver to be able to use the ipoib_options. It deals with the two flows from the .ndo: ipoib_open and ipoib_stop. The code is rearranged as follows: * All operations which deal with the hardware resources, (for example change QP state, post-receive etc.) are performed in one place. * All operations that are control oriented (like restart multicast task, start the reap_ah etc.) are performed in separate place. The functions that deal with the hardware resources now located at __ipoib_ib_dev_open for the ipoib_open flow and __ipoib_ib_dev_stop for ipoib_stop.
