Infocast Latency in IGMP v2 Network

KreaTV is capable of running in both IGMP v3 and IGMP v2 networks, and will run with the following behaviour by default: detect and use IGMP v3 if router and other network devices support it, and fall back to use IGMP v2 if a router or network device which is only IGMP v2 capable is detected. It is known that the fallback latency from IGMP v3 to IGMP v2 in the STB will possibly be up to 1 minute. This may result in the STB getting the Whitelist and other information objects from Infocast server a bit late, which in turn may cause the white screen to be visible during the startup of the browser.

This can be avoided by forcing KreaTV to always use IGMP v2. Do this by adding the following to the bootimage config file:

kreatv-option-procfs:sys/net/ipv4/conf/eth0/force_igmp_version=2
