drivers/net/arcnet/arcnet.c: use time_* macros

The functions time_before, time_before_eq, time_after, and time_after_eq are
more robust for comparing jiffies against other values.

So use the time_after() macro, defined in linux/jiffies.h, which deals with
wrapping correctly.

3c509: convert to isa_driver and pnp_driver

Convert 3c509 driver to isa_driver and pnp_driver.  The result is that
autoloading using udev and hibernation works with ISA PnP cards.  It also adds
hibernation support for non-PnP ISA cards.

xcvr module parameter was removed as its value was not used.

Tested using 3 ISA cards in various combinations of PnP and non-PnP modes.
EISA and MCA only compile-tested.

And redirect sock_prot_inuse_add and _get to use one.

As far as the dereferences are concerned. Before the patch we made
1 dereference to proto->inuse.add call, the call itself and then
called the __get_cpu_var() on a static variable. After the patch we
make a direct call, then one dereference to proto->inuse_idx and
then the same __get_cpu_var() on a still static variable. So this

This is not per-net yet, but I will deliberately make NET_NS=y case
separated from NET_NS=n one, since it'll cost us one-or-two more
