dibs: Create drivers/dibs Create the file structure for a 'DIBS - Direct Internal Buffer Sharing' shim layer that will provide generic functionality and declarations for dibs device drivers and dibs clients. Following patches will add functionality.

dibs: Define dibs loopback The first stage of loopback-ism was implemented as part of the SMC module [1]. Now that we have the dibs layer, provide access to a dibs_loopback device to all dibs clients. This is the first step of moving loopback-ism from net/smc/smc_loopback.* to drivers/dibs/dibs_loopback.*. One global structure lo_dev is allocated and added to the dibs devices. Follow-on patches will move functionality. Same as smc_loopback, dibs_loopback is provided by a config option. Note that there is no way to dynamically add or remove the loopback device. That could be a future improvement. When moving code to drivers/dibs, replace ism_ prefix with dibs_ prefix. As this is mostly a move of existing code, copyright and authors are unchanged.
