      I have been trying to figure out why I was not seeing more than one netisr thread on my system after upgrading to a 2.5 snapshot.

      Finally noticed that I was seeing this message in the during boot.

      netisr_init: forcing maxthreads to 1 and bindthreads to 0 for device polling

      Took a look at the build options and noticed the polling is enabled in the 12.0 kernel while it looks like it was disabled previously in 11.2.

      https://github.com/pfsense/FreeBSD-src/blob/RELENG_2_5/sys/amd64/conf/pfSense

      options DEVICE_POLLING

      Can someone take a look at this and confirm for me if I am understanding this correctly.

        it was present inside RELENG_2_3_4, it was removed from RELENG_2_4 and RELENG_2_4_4( "loos-br Remove deprecated option DEVICE_POLLING from pfSense kernel. ") now it's back, as you have noticed, inside RELENG_2.5 conf

          I've removed it from 2.5.0 kernel config. Thanks!

            Just upgraded to the latest snapshot, 2.5.0-DEVELOPMENT-amd64-20190520-1137, and can confirm that this now seems to be working properly. Thank you for the quick response!
