In case an invalid mux id is passed, an invalid device lookup is
done leading to passing on the packet to stack incorrectly rather
than consuming them.

The delay argument in schedule_delayed_work(struct delayed_work
*dwork, unsigned long delay) API is jiffies. The system tick for
seems to be 100Hz, so the minimum time resolution for the work to
be scheduled is 10ms.
Switch to hrtimer to achieve 3 ms granularity with a current timer
of 1ms for the flush thread. A workqueue is immediately scheduled
in the same context after this timer expiry to do the tx work.

Skipping UL aggregation if the packet was linear was causing out
of order packets. If linearization fails, pass up the packet as is.
Also skip padding if using version 3 or v4 when using UL aggregation.

ICMP packets could be potentially stuck behind aggregated traffic
if UL aggregation is enabled on rmnet_data. This results in
increased latencies during ping tests as the workqueues for these
packets are scheduled at non deterministic times.

Global variables are no longer assigned values. Instead
flush meta data is handled and tracked at per end
point basis.
Reduce the number of register reads for timer. Leverage
value which has already been read earlier in function.

Using UL aggregation for non linear data is not efficient since
we are copying data from a non linear segment to a linear buffer.
As a result, we lose the advantages of GSO and increase our RTT.

We clean up the logical end points only for the un-registering device
in bridge mode. However, the other physical end point's local end
point still points to the the un-registered device.
This may lead up to a crash if one of the physical devices in bridge
mode is un-registered. Fix this by unsetting the local endpoint.
It is still possible that packets in a different context across cores
might try to access this data. This usually manifests as packets
requesting a very large headroom. Handle this by dropping these stale
skb's.

Port single flow dynamic GRO changes into rmnet driver. This
feature uses configurable parameters that determine when GRO
should be flushed based on both timing and receive byte count.
Although the parameters are initially set, they dynamically
fluctuate based on incoming traffic.

Some creators of skb's may fail to set sufficient headroom or
tailroom to stamp the MAP header or tailroom respectively when
transmitting packets to rmnet_data.
In these cases, rmnet_data was failing to free these packets which
lead to out of memory scenarios in low memory targets. Free these
skb's in these scenarios.
