This ioctl provides a shorter route to enable/disable flow
on a given qdisc when compared to the traditional NETLINK
based communication. It is known to improve throughput when
data flow is throttled at a higher rate.

which allow ethernet packets to be exchanged with the cellular network, once
an appropriate data connection is established.

[ARM] msm_rmnet: HACK: do not count ARP packets
The android network traffic watchdog is tricked into thinking that
data traffic is working at times when it isn't, due to ARP traffic
between the apps and modem processor. Don't count ARP packets in
link statistics to avoid this problem.
[ARM] msm: rmnet: Add stat tracking for number of radio wakeups occur.
There are two paramaters that appear for all rmnet devices.
rmnet0 for example:
/sys/devices/virtual/net/rmnet0/timeout (RW)
/sys/devices/virtual/net/rmnet0/wakeups (RO)
timeout is configured by userspace for the proper network timeout values
wakeups is the number of radio wakeups that occured.
By default timeout is zero which means the stats are disabled.
MSM_RMNET_DEBUG must be set.
