Note that the only bits which are always treated as non-data are the 8 label bits (well, and the parity bit #31). The 2 SDI bits (#8, #9) may be used as data bits when a high resolution is needed, like Lat/Long encoded in binary words 310 and 311. I wouldn't make any assumption on what's on those 2 bits; i.e. they're not always "source/destination". -- Aleksander https://aleksander.es -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
