Baseline: what do you expect this option setting to do when used with
the 3c905_ (no suffix)?

Note that the 3c905 has an external MII transceiver (trasceiver type 6),
while the 3c905B and 3c905C have on-chip transceivers (transceiver type 8).

I would say that the driver is working as you directed it to.

You should not set driver options unless you have a non-standard
configuration.  Setting driver options "just to make sure" is a common
source of problems.

I suspect that just removing the module options will restore correct
operation.
