--
Dissecting HPAV-1.1 Tone Map Characteristics Req/Conf (0xA070/0xA071) was not
correct.
Also found that MMType 0xA070/0xA071 is used for the Tx ToneMaps and the MMType
0xA090/0xA091 for the Rx ToneMaps. Added types and dissector for the Rx MMType.
Although the Rx-Conf-Structure is almost identical to the Tx is did duplicate
the dissector code to avoid mixups.
Added some additional Infos to the carrier dissector output (Carrier#,
#Modulated-Bits, Average#Modulated-Bits/Carrier).
Also extended the homeplug_av_tone_map_vals with 0x08 for 12bit 4096-QAM (the
AR74xx should support this kind of modulation) and changed the mask to 0x0f
accordingly.
Thanx,
Guus
