62badeeeb9 dibs: Improve DIBS prompts and help texts
The Kconfig prompts for the DIBS options read:

    DIBS support (DIBS) [N/m/y/?]
      intra-OS shortcut with dibs loopback (DIBS_LO) [N/y/?]

Clarify the DIBS prompt by expanding the acronym.
Capitalize the first character of the DIBS_LO prompt.
While at it, join the first two lines of the DIBS help text into a real
sentence.

cb990a45d7 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.
