I think it could be done – not sure what the use case would be, other than creating a list. /Anders On Wed, Oct 21, 2020 at 9:34 AM Anders Broman via Wireshark-dev <wireshark-dev@wireshark.org <mailto:wireshark-dev@wireshark.org> > wrote: Hi, In the developers den we discussed the possibility of disabling unneeded protocols and I brought up the idea of protocol groups. If there is interest in this feature I would need help with the GUI part – volunteers? As a PoC I was thinking of something along these lines. Turn all protocols of – enable the group “basic” which would then be the basic protocols you would need in most cases like Ethernet -VLAN-IP4/IPv6-TCP UDP SCTP ICMP ICMP6 ARP more? We don’t need a comprehensive list here and now these might do for the PoC. Once the basic group is there we might start to look at large groups of specialized protocols most people would want to turn off like USB Bluetooth ZigeBee, telco(?) might be candidates. This would be the API to register in a group, only allowed group names(we make list) to be accepted at registry time, possibly Have a register group name routine? But the poc may not have to be more complicated than this. --- a/epan/proto.c +++ b/epan/proto.c @@ -343,21 +343,22 @@ static header_field_info hfi_text_only = { "Text item", "text", FT_NONE, BASE_NONE, NULL, 0x0, NULL, HFILL }; int hf_text_only = -1; -/* Structure for information about a protocol */ +/** Structure for information about a protocol */ struct _protocol { - const char *name; /* long description */ - const char *short_name; /* short description */ - const char *filter_name; /* name of this protocol in filters */ - GPtrArray *fields; /* fields for this protocol */ - int proto_id; /* field ID for this protocol */ - gboolean is_enabled; /* TRUE if protocol is enabled */ - gboolean enabled_by_default; /* TRUE if protocol is enabled by default */ - gboolean can_toggle; /* TRUE if is_enabled can be changed */ - int parent_proto_id; /* Used to identify "pino"s (Protocol In Name Only). + const char *name; /**< long description */ + const char *short_name; /**< short description */ + const char *filter_name; /**< name of this protocol in filters */ + const char* group_name; /**< name of the "group" this protocol belongs to */ + GPtrArray *fields; /**< fields for this protocol */ + int proto_id; /**< field ID for this protocol */ + gboolean is_enabled; /**< TRUE if protocol is enabled */ + gboolean enabled_by_default; /**< TRUE if protocol is enabled by default */ + gboolean can_toggle; /**< TRUE if is_enabled can be changed */ + int parent_proto_id; /**< Used to identify "pino"s (Protocol In Name Only).
