  I have same problem (every one of 100-200 frames) on on-board if_em:

em0 at pci0:0:25:0:        class=0x020000 card=0x82681043 chip=0x10bd8086 rev=0x02 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82566DM-2 Gigabit Network Connection'
    class      = network
    subclass   = ethernet
