I added this check to tools/check_typed_item_calls.py --mask

I am hoping that someone will recognise a protocol they know and check out what is reported, and to be able to work out if this check makes sense to do.

Quite a few of the current cases have to do with multi-bit reserved fields, where I guess you don't want to know the value the bits represent, but just to see if any were set...  Even then, it may be quicker to see a value that is zero or not rather than manually check each bit.

The first case (ansi_a_bsmap.hho_params.enc_mode), has 2 bits set but uses VALS(&tfs_enabled_disabled).  But looking at http://www.3gpp2.org/Public_html/Specs/A.S0014-0_v1.0.pdf, the only valid values are 00 and 01, so this is OK.

So in the case of packet-mac-nr.c, I would want to make the field a FT_UINT8 instead (the first 2 bits of byte are reserved).

For packet-zbee-zcl.c, it wants to show the values of all of the bits in a byte, and TFS(&tfs_true_false) is used.  I don't even know what the filter value would be here (the value of the whole byte?).

Here is the current output:
