I have this problem on some ethernet cards, such as:
em0@pci0:14:0:0: class=0x020000 card=0x109a15d9
chip=0x109a8086 rev=0x00 hdr=0x00
vendor = 'Intel Corporation'
device = '82573L Intel PRO/1000 PL Network Adaptor'
class = network
subclass = ethernet
em0@pci0:6:0:0: class=0x020000 card=0x108c15d9 chip=0x108c8086
rev=0x03 hdr=0x00
vendor = 'Intel Corporation'
device = '82573E Intel Corporation 82573E Gigabit Ethernet
Controller (Copper)'
class = network
subclass = ethernet

How I can enable this processing?

Output of ifconfig both:
