https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D265714 --- Comment #1 from mike@sentex.net --- Note, running the same test with a different set of boxes that use the i226 version of the PHY works just fine. After ~ 18hrs of testing, I was not abl= e to get the transmitting NIC to drop carrier under load igc0@pci0:2:0:0: class=3D0x020000 rev=3D0x04 hdr=3D0x00 vendor=3D0x8= 086 device=3D0x125c subvendor=3D0x8086 subdevice=3D0x0000 vendor =3D 'Intel Corporation' class =3D network subclass =3D ethernet bar [10] =3D type Memory, range 32, base 0x80200000, size 1048576, en= abled bar [1c] =3D type Memory, range 32, base 0x80300000, size 16384, enab= led cap 01[40] =3D powerspec 3 supports D0 D3 current D0 cap 05[50] =3D MSI supports 1 message, 64 bit, vector masks=20 cap 11[70] =3D MSI-X supports 5 messages, enabled Table in map 0x1c[0x0], PBA in map 0x1c[0x2000] cap 10[a0] =3D PCI-Express 2 endpoint max data 256(512) FLR RO NS max read 512 link x1(x1) speed 5.0(5.0) ASPM disabled(L1) ecap 0001[100] =3D AER 2 0 fatal 0 non-fatal 0 corrected ecap 0003[140] =3D Serial 1 7c2be1ffff131e81 ecap 0018[1c0] =3D LTR 1 ecap 001f[1f0] =3D Precision Time Measurement 1 ecap 001e[1e0] =3D L1 PM Substates 1 ---<<BOOT>>--- Copyright (c) 1992-2021 The FreeBSD Project.
