Info: Kernel parameter values are read during runtime using "sysctl()" function and stored in "ifmibdata". "ifmibdata" contains the "ifmd_data" table. Under this "ifmd_data" we can get the statistics informations like out/in packets, packet error, out/in packet bytes, packet collision. when we try to read "ifi_ibytes" (i.e in packet bytes/sec) the value is not getting updated (always remains zero) during downloading but "ifi_obytes" (i.e out packet bytes/sec) value is getting updated.
Note : This is observed when data connection is connected via datacard (wireless network adapter).
** This issue is still observed in latest release [Developer Beta 6]
