I wanted to be able to search on bit-oriented fields by using searches like
scsi.cdb.control.naca but that is currently not possible. I also want the
parameter lists for Persistent Reservation command dissected properly.

In addition, Chris Maynard pointed out:

" It looks like there are other bit-oriented fields besides
hf_scsi_control that could benefit from this as well: hf_scsi_inquiry_flags,
hf_scsi_modesel_flags, ...

There also seem to be a lot of proto_tree_add_text() calls (I count 186 of
them).  I haven't looked at them all, but I suspect most would be better added
using proto_tree_add_item() so those fields could be filterable as well."

As I change these things I will post patches here for possible inclusion in a
future version of Ethereal, errr, I mean Wireshark.
