ethernet chips. This driver is pretty simple, however it contains
special DSP initialization code which is needed in order to get
the chip to negotiate a gigE link. (This special initialization
may not be needed in subsequent chip revs.) Also:
- Fix typo in if_rlreg.h (RL_GMEDIASTAT_1000MPS -> RL_GMEDIASTAT_1000MBPS)
- Deal with shared interrupts in re_intr(): if interface isn't up,
return.
- Fix another bug in re_gmii_writereg() (properly apply data field mask)
- Allow PHY driver to read the RL_GMEDIASTAT register via the
re_gmii_readreg() register (this is register needed to determine
real time link/media status).
