- The values of lp_10fdx_cap, lp_10hdx_cap, lp_100fdx_cap, lp_100hdx_cap, lp_1000fdx_cap,
lp_1000hdx_cap, lp_pauseTX, lp_pauseRX, lp_autoneg_cap are effective, only when
communication is done without Autonegation or Autonegation has not been established.

Search for the device path of 'FJSV' or 'pwga' in the OK prompt screen.
Example
