With format-security errors turned on, GCC picks up the use of sprintf with a format parameter not being a string literal. Simple uses of sprintf are also converted to use strcpy.

|
|
* PHYs are the two on-board 1Gb ports. There are no RGMII PHY on board.
|
|
* The 10Gb XGMII PHY is provided via the XAUI riser card. There is only
|
|
* one Fman device on B4860. The SERDES configuration is used to determine
|
|
* where the SGMII and XAUI cards exist, and also which Fman MACs are routed
|
|
* to which PHYs. So for a given Fman MAC, there is one and only PHY it
|
|
* connects to. MACs cannot be routed to PHYs dynamically. This configuration
|
|
* is done at boot time by reading SERDES protocol from RCW.
