Remove the cnw(4) driver. No one responded to calls to test it on current@

and stable@. It also is a driver for an older non-802.11 wireless PC card that is quite slow in comparison to say, wi(4). I know Warner wants this driver axed as well.

Make cnw(4) MPSAFE:

- Add a mutex to the softc and use it to lock the softc and device hardware. - Use a private timer to replace if_watchdog/if_timer. - Use if_printf() rather than if_xname. - Setup interrupt handler after ether_ifattach().

Grr, restore some useful comments that were only in the NetBSD code.

Remove NetBSD and FreeBSD 4.x code from this driver in preparation for

2008-05-28T19:44:46Z

adding locking, etc.

Catchup to filters by piso.

Since DELAY() was moved, most #includes have been

unnecessary.

Make sure that we call if_free(ifp) after bus_teardown_intr. Since we

2005-09-19T03:10:21Z

could get an interrupt after we free the ifp, and the interrupt handler depended on the ifp being still alive, this could, in theory, cause a crash. Eliminate this possibility by moving the if_free to after the bus_teardown_intr() call.

Fix "struct ifnet" leaks when attach() fails in the middle.

Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and

2005-08-09T10:20:02Z

IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to ifnet.if_drv_flags. Device drivers are now responsible for synchronizing access to these flags, as they are in if_drv_flags. This helps prevent races between the network stack and device driver in maintaining the interface flags field. Many __FreeBSD__ and __FreeBSD_version checks maintained and continued; some less so.
