changing shared macro doesn't effect other atomic_ops because
(*ptr [+|^] delta) and (delta [+|^] *ptr) have same result.
atomic_sub_*() haven't used because non standard API?
Non-OF environment.
The Saturn multi port card has only one VPD ROM and all ports share it.
If the card has four port, it has four "local-mac-address" entries.
Before this commit, the code keep the last one and use it for all ports.
The Saturn four port card has three bridge.
e.g.
----------------
003:02:0: Intel S21152BA,S21154AE/BE PCI-PCI Bridge (PCI bridge)
004:00:0: Intel S21152BA,S21154AE/BE PCI-PCI Bridge (PCI bridge)

005:01:0: National Semiconductor Saturn (ethernet network, revision 0x30)
006:02:0: National Semiconductor Saturn (ethernet network, revision 0x30)
006:03:0: National Semiconductor Saturn (ethernet network, revision 0x30)
----------------
The card assign each port's PCI device number to match the port number.
Use it as the offset of "local-mac-address". Almost the same as FreeBSD.

As far as I can tell, alpha blending only works between overlay channels,
and not between layers on a channel. Unfortunately, RT-Mixer1 only has
a single UI channel, so this feature is limited to RT-Mixer0.
and provide methods to the private softc
- Provide a function for constructing a RF_Raid_t from an RF_Config_t
- Factor out the big inline ioctl code into functions
since the request structs are different and the row in the old struct is
the col in the new one).
- Restructure the way compat modules are loaded so that we only load them
for the ioctls that need them. Put a comment explaining why...
- Set retcode after loading compat (now that the fail disk passthrough
hack is gone), so that various ioctls don't always fail.
Restore the original behavior before merging the compat refactoring branch.
Now:
- no compat_10 -> perform pathbuf_copyin() and report EFAULT
- compat_10 and error -> report error
- compat_10 and success -> return file descriptor for "."
PR kern/53948
- Move the stub routines from zfs_stub.c to zfs_ctldir.c and
remove now empty file zfs_stub.c
- Add stub routines for zfsctl_loadvnode() to initialize control
nodes and zfsctl_snapshot() to retrieve ".zfs/snapshot".
- Add an initial vnode operations vector for control nodes.
- Implement lookup into ".zfs" and lookup ".." from ".zfs/snapshot/<snap>".
- Change nodeid of mounted snapshots to the snapshot object id.
- Respect "-u" flag to "zfs rename <snapshot> ...".
