config TIVA_PHYSR_ALTCONFIG
bool "PHY Status Alternate Bit Layout"
default n
---help---
Different PHYs present speed and mode information in different ways. Some
will present separate information for speed and mode (this is the default).
Those PHYs, for example, may provide a 10/100 Mbps indication and a separate
full/half duplex indication. This options selects an alternative representation
where speed and mode information are combined. This might mean, for example,
separate bits for 10HD, 100HD, 10FD and 100FD.
