--- Comment #4 from Franco Fichtner <franco@opnsense.org> ---
la is being read and modified after unlock with the attached patch.  Though it
looks like arprequest() may indeed work as expected without the lock held.  Not
sure if unlock/lock around arprequest is advisable; there may be a more
fundamental issue with the code block itself?
