| |
For some of the chip-ops where sbe needs to collect trace information, sbe can take a long time (>30s) to respond. Currently these chip-ops will timeout as the start of response timeout defaults to 10s.
Instead of default value, use specified value. The require timeout value will be set using ioctl.
