sflow - ifindex parsing

 Hi All,

Recently I enabled sFlow on HP Procurve 2800 series switch. While parsing
the sFlow packets I found a big Ifindex value (3F FF FF FF). I know
Ifindex can not have this(1073741823) value. I have given the packet
dump also. Am i missing something? Please help me.

Regards
Ram
