Use the -l drvr option to qcc to link against this library.
You can use hwitag_find_phyaddr() to find one or more PHY addresses associated with the device at hwi_off in the hwinfo section of the system page.
Some devices contain multiple PHY addresses. You can retrieve all of them by using the phy_idx parameter as follows:
The PHY address, or -1 on error.
