This class is derived from class Packet. The fields defined below are a direct interpretation of the v3 Membership Query Message. Fields 'type' through 'qqic' are directly assignable. For 'numsrc', do not assign a value. Instead add to the 'srcaddrs' list to auto-set 'numsrc'. To assign values to 'srcaddrs', use the following methods:: c = IGMPv3() c.srcaddrs = ['1.2.3.4', '5.6.7.8'] c.srcaddrs += ['192.168.10.24'] At this point, 'c.numsrc' is three (3) 'chksum' is automagically calculated before the packet is sent.
