net: qualcomm: rmnet: Set pacing shift
The real device over which the rmnet devices are installed also
aggregate multiple IP packets and sends them as a single large
aggregate frame to the hardware. This causes degraded throughput
for TCP TX due to bufferbloat.
To overcome this problem, pacing shift value of 8 is set using the
sk_pacing_shift_update() helper. This value was determined based
on experiments with a single stream TCP TX using iperf for a
duration of 30s.
Pacing shift | Observed data rate (Mbps)
10 | 9
9 | 140
8 | 146 (Max link rate)
