Re: [pfSense-discussion] Polling?
ah, man polling I forgot about that one *blushes* thanks! - Original Message - From: Scott Ullrich [EMAIL PROTECTED] To: discussion@pfsense.com Sent: Wednesday, February 15, 2006 7:32 AM Subject: Re: [pfSense-discussion] Polling? SUPPORTED DEVICES Device polling requires explicit modifications to the device drivers.

Re: [pfSense-discussion] Polling?
One more question about polling, in PfSense, if I turn on polling, but I have 1 interface that doesn't support it, does that mean they all don't have polling turned on? Or is it activated just for the ones that do support it, and the ones that don't use the regular interupt system? - Original Message - From: Scott Ullrich [EMAIL PROTECTED] To: discussion@pfsense.com Sent: Wednesday, February 15, 2006 7:32 AM Subject: Re: [pfSense-discussion] Polling?

There was a bug that I fixed and will show up in the next snapshots where none of the interfaces was being enabled.
