ndis: Add debug support to disable RNDIS Multipacket Feature
This change adds module param which allows to disable RNDIS
Multi-packet Feature (Aggregation support in Downlink path)
as this feature is enabled by default.
To disable use this param before moving to RNDIS Composition:
echo 1 > /sys/module/g_android/parameters/rndis_multipacket_dl_disable
Also counts errors as Rx errors if received RNDIS packets are
not following RNDIS message format as those packets are being
discarded.
