Subject: [PATCH] [resend] 3c509: convert to isa_driver and pnp_driver v5
Hello,
this patch converts 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.
