Wireshark · Wireshark-dev: Re: [Wireshark-dev] need help on RRM capability info

[wsgd <wsgd@xxxxxxx>]

Hello,

Into Tag definitions, you said :
- FT_BOOLEAN, 40 bits  = 5 bytes
- mask goes to 0x0800 and so on which is 2 bytes long (and so on)

Into proto_tree_add_boolean calls, you said : length = 1 byte
-> incoherent
-> proto_tree_add_boolean could not apply mask > 0x00ff

So try :
- proto_tree_add_boolean calls with length = 5 bytes   (NB: not sure 
value above 4 is accepted, must check)
- do not increment offset
