Broadcom ethernet driver tg3 driver failes on kernel 4.15.x

[frli8848]

After upgrading to kernel 4.15.2 and 4.14.15 I get:

Code: Select all

Apr  3 11:19:37 fl-mbp kernel: tg3.c:v3.137 (May 11, 2014)
Apr  3 11:19:37 fl-mbp kernel: tg3 0000:0e:00.0: phy probe failed, err -19
Apr  3 11:19:37 fl-mbp kernel: tg3 0000:0e:00.0: Problem fetching invariants of chip, aborting

This is on Apple hardware: MacBook Pro 2013 and a Thunderbolt Display.

Can help this?

The broadcom.ko module was not enabled by default in the kernel. But enabling:[/code]

Code: Select all

BROADCOM_PHY=m

does not help. The broadcom module is not loaded at boot and even if I remove the tg3 module and do:

Code: Select all

fl-mbp ~ # rmmod tg3
fl-mbp ~ # modprobe broadcom
fl-mbp ~ # modprobe tg3

I get

Got the tg3 driver to work with kernel 4.16.12 and the ethernet port in the Apple Thunderbolt Display by building both thunderbolt and the tg3 drivers as modules:

Building thunderbolt in the kernel causes the tg3 driver to fail with the Apple Thunderbolt Display:
