Use the device sysctl tree instead of rolling our own. Some of the

sysctls were global (hw.fxp_rnr and hw.fxp_noflow), all of them are
now per-device.  Sample output of "sysctl dev.fxp0" with this patch,
with the standard %foo nodes removed :

dev.fxp0.int_delay: 1000
dev.fxp0.bundle_max: 6
dev.fxp0.rnr: 0
dev.fxp0.noflow: 0
