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.
