- Make multicast work - Fix (some of) the watchdog timeouts after card reset - Add support for CE2, CEM28 and CEM33 cards - General code cleanup Any card that worked previously should still work, as well as a lot that didn't. The driver is not yet style(9) compliant; those changes are forthcoming, once the functional changes are done. PR: kern/50644 Reviewed by: imp Approved by: imp
