priv does not disable Intel X7xx firmware LLDP on FreeBSD

[neirbowj]

Bug description

a74fd8c only disables the Intel 700 series firmware LLDP process on Linux. See also: 45f3c77

Steps to reproduce the problem

1. Install the net-mgmt/lldpd port on a FreeBSD machine equipped with an Intel X7xx NIC (see ixl(4))
2. Enable the lldpd service (e.g. sysrc lldpd_enable=YES)
3. Start the lldpd service (e.g. service lldpd start)
4. Run sysctl dev.ixl | grep lldp
5. Observe that the value of each dev.ixl.N.fw_lldp sysctl is 1.

Expected outcome

lldpd has disabled the ixl firmware LLDP process.

Current outcome

lldpd leaves the ixl firmware LLDP enabled.

Additional information

Note that this is from a local ports tree where the net-mgmt/lldpd update from 1.0.14 to 1.0.18 has not yet been submitted/accepted upstream.
