It is already semi-aware of BNFTP:

packet-bnetp/src/packet-bnetp.lua

Lines 66 to 72 in 4c7ae58

	local f_type = ProtoField.uint8("bnetp.type","Header Type",base.HEX, {
	[0x1] = "Game protocol request",
	[0x2] = "FTP protocol request",
	[0x3] = "Chat protocol request",
	[0xF7] = "W3IGP",
	[0xFF] = "BNCS",
	})

It just needs to be fixed.

More specifically, it correctly identified ver-IX86-5.mpq as FTP_PROTOCOL (BNFTP), however it did not identify icons-WAR3.bni as such.

It is aware of bnftp yes but it does not have the protocol implementation, just detects the header. It needs to be implemented for bnftp v1 and v2. I'll give it a go.
