now we are working on separate iwlagn driver into two layers (upper and

doing so, the single driver can handle different bus and different core
architecture. Having the share data structure (priv->shrd->foo) between
two layers is for that reason (loosely couple).

You did not explained reason for introducing iwl_shared structure,
actually you confirmed it is useless. You should simply share iwl_priv
on any layer you have.
