There is a newer driver in rtems-libbsd with a FreeBSD copyright dated between 2006 and 2008: [dufault@litho9099 rtems-libbsd]$ ls freebsd/sys/dev/smc if_smc.c if_smcreg.h if_smcvar.h [dufault@litho9099 rtems-libbsd]$ This is the new stack, correct? That driver is what I was thinking of looking at porting to the old stack. I will spend some time trying to figure out what's up with the current driver.
