Use FALSE, rather than 0, as the last argument to

Fix one "proto_tree_add_uint()" call that was supposed to be a
"proto_tree_add_item()" call.
Use "%u", not "%d", to display unsigned values.

Move the handling of the Network_Header for full FC frames into the FC
dissector, and have the LLC dissector register itself as the dissector
for IP-over-FC frames, as the payload is just an LLC 802.2 header plus
payload for the protocol specified by that header.
In the dissector for IP-over-FC as a Wiretap link-layer type, have its
top-level item be a protocol item rather than a text item, and don't
register it as the dissector for IP-over-FC frames from the FC dissector
- it assumes what it's handed includes the Network_Header, but for full
FC frames, the FC dissector has already consumed the Network_Header.
Move the definitions of the value_string tables out of the header file;
most of them are used only in one file, so define them in that file, and
for "fc_fc4_val", define it in "packet-fc.c", make it not static, and
declare it in "packet-fc.h".
Use FALSE, rather than 0, as the last argument to
"proto_tree_add_item()" calls that add a big-endian value.
Fix one "proto_tree_add_uint()" call that was supposed to be a
"proto_tree_add_item()" call.
Use "%u", not "%d", to display unsigned values.

dissector, and have the LLC dissector register itself as the dissector
for IP-over-FC frames, as the payload is just an LLC 802.2 header plus

In the dissector for IP-over-FC as a Wiretap link-layer type, have its
top-level item be a protocol item rather than a text item, and don't
register it as the dissector for IP-over-FC frames from the FC dissector
- it assumes what it's handed includes the Network_Header, but for full
FC frames, the FC dissector has already consumed the Network_Header.
Move the definitions of the value_string tables out of the header file;
most of them are used only in one file, so define them in that file, and
for "fc_fc4_val", define it in "packet-fc.c", make it not static, and
declare it in "packet-fc.h".
Use FALSE, rather than 0, as the last argument to
"proto_tree_add_item()" calls that add a big-endian value.
Fix one "proto_tree_add_uint()" call that was supposed to be a
"proto_tree_add_item()" call.
Use "%u", not "%d", to display unsigned values.
