Commit 4a16579f authored by Robert Sprowson's avatar Robert Sprowson Committed by ROOL

MII function updates

These change the prototypes of the MII read/write functions, so that the MII headers are at the same revision as those used by EtherGENET.
if_cpsw.c: Updated to NetBSD's revision 1.24
miivar.h: Updated to NetBSD's revision 1.69
mii.h: Updated to NetBSD's revision 1.27
glue.c: Refactor to use new function prototypes
glue.h: Merge macro improvements from EtherGENET-0_02, remove one made redundant now

Version 0.05. Tagged as 'EtherCPSW-0_05'
