- Add a mutex to the softc and use it to protect the softc and device
hardware.
- Setup interrupt handler after attaching device to network stack.
- Use device_set_desc() rather than device_quiet() plus a manual printf
that simulates the normal probe printf.
- Axe next_sbni_unit and instead just leave room for two sbni devices for
each bus attachment.
- Don't bzero the already-zero'd softc.
- Add a detach method to the PCI driver.
- Add a lock to protect the list of available devices used to chain
interrupt handlers for dual port ISA cards.
- Remove unused watchdog routine.
- If if_alloc() fails, make sbni_attach() return an error rather than
panic'ing.
- Consolidate code to free bus resources into sbni_release_resources().
- Clear IFF_DRV_RUNNING|OACTIVE in stop() routine instead of in callers.
- Let ether_ioctl() handle SIOCSIFMTU.
network layer (ether).
- Don't abuse module names to facilitate ifconfig module loading;
such abuse isn't really needed. (And if we do need type information
associated with a module then we should make it explicit and not
use hacks.)
- bus_space'ify
- generate fake ethernet address using read_random() instead of reading
from timer i/o ports
Other minor fixes:
- remove "hack" in connect_to_master()
- use M_ZERO
- remove unused variable in sbni_ioctl()
- properly release irq in sbni_attach_isa() on attach errors
