qed: Cleaner seperation of LL2 inputs
A LL2 connection [qed_ll2_info] has a sub-structure of type qed_ll2_conn that contain various inputs for ll2 acquisition, but the connection also utilizes a couple of other inputs. Restructure the input structure to include all the inputs and refactor the code necessary to populate those. Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S.
