USB: serial: sierra driver performance improvements
- Version number set to 1.3.4
- Increased the number of input/output URBs for improved performance
(numbers based on an measurement study triggered by a user request).
We performed the testing using a network simulator that provided full
speeds in the uplink and downlink directions and this combination of
URBs provided the best throughput.
