pfSense

In order to support bwi and bwn wifi cards a patch from upstream FreeBSD. This apparently has been an issue since 2010 when the patch was applied to the kernel, it does not seem to appear in the kernel built for pfsense. That said it does appear to be a simple change of an equate, bumping FIRMWARE_MAX from 30 to 50 in sys/kern/subr_firmware.c

It seems this patch was only applied to the FreeBSD9 series kernels but there are reports on the forum of it working with the 8.3 series. It is a rather simple change as it is.
