--- Comment #20 from Stefan Thurner <thurners at nicsys.de> ---
Hi,

I'm facing this problem on 1 of 2 installed em interfaces, too.

System:
FreeBSD 12.0-STABLE r344823 amd64

NICs:
em0 at pci0:0:25:0:        class=0x020000 card=0x102e17aa chip=0x15028086 rev=0x04
hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82579LM Gigabit Network Connection (Lewisville)'
    class      = network
    subclass   = ethernet

em1 at pci0:2:10:0:        class=0x020000 card=0x002e8086 chip=0x100e8086 rev=0x02
hdr=0x00
    vendor     = 'Intel Corporation'
    device     = '82540EM Gigabit Ethernet Controller'
    class      = network
    subclass   = ethernet

Problem:
Mar  7 20:49:06 hydrogen kernel: em1: link state changed to DOWN
Mar  7 20:49:07 hydrogen kernel: em1: TX(0) desc avail = 1024, pidx = 0
Mar  7 20:49:12 hydrogen syslogd: last message repeated 3 times
Mar  7 20:49:14 hydrogen kernel: em1: link state changed to UP
Mar  7 20:49:15 hydrogen kernel: em1: TX(0) desc avail = 1020, pidx = 4
Mar  7 20:49:15 hydrogen kernel: em1: link state changed to DOWN
Mar  7 20:49:16 hydrogen kernel: em1: link state changed to UP
Mar  7 20:49:24 hydrogen kernel: em1: link state changed to DOWN
Mar  7 20:49:26 hydrogen kernel: em1: link state changed to UP
Mar  7 20:49:27 hydrogen kernel: em1: link state changed to DOWN
Mar  7 20:49:28 hydrogen kernel: em1: TX(0) desc avail = 1024, pidx = 0
Mar  7 20:49:30 hydrogen syslogd: last message repeated 1 times
Mar  7 20:49:32 hydrogen kernel: em1: link state changed to UP
Mar  7 20:49:34 hydrogen kernel: em1: link state changed to DOWN
Mar  7 20:49:36 hydrogen kernel: em1: TX(0) desc avail = 1024, pidx = 0
Mar  7 20:49:50 hydrogen syslogd: last message repeated 8 times
Mar  7 20:49:52 hydrogen kernel: em1: link state changed to UP
Mar  7 20:49:52 hydrogen kernel: em1: TX(0) desc avail = 1024, pidx = 0
Mar  7 20:49:52 hydrogen kernel: em1: link state changed to DOWN
Mar  7 20:49:54 hydrogen kernel: em1: link state changed to UP

em0 (82579LM) does work without problems.
