Ethernet (wired) is not detected, or wrong non working driver is selected (false detection)

After uninstalling broadcom-wl-dkms and reloading modules like so:

```
rmmod tg3
modprobe broadcom
modprobe tg3

Thanks for reporting. It could be that too many modules are blacklisted when installing the broadcom-wl-dkms package. I'm not on a machine with Broadcom hardware right now.

Do you happen to know if not blacklisting one or more of these kernel modules in broadcom-wl-dkms.conf and then rebooting fixes this issue?

I added a note to the .install file output + blacklisted the tg3 kernel module in broadcom-wl-dkms.conf.

Unfortunately, broadcom-wl-dkms is unmaintained non-open-source software with a custom license. It has been patched heavily since Linux 4.7 and it's not straightforward to make it play well with other parts of Linux.

Please re-open this issue if there are better solutions available.

Why did we blacklist tg3? It is needed for ethernet.

Related to  FS#70907 . This change broke ethernet on my machine. I need tg3 and this driver on my machine. I propose that we back out this change, and if tg3 is conflicting on the reporter's machine, the correct approach is to blacklist tg3 on that machine.

On my machine, this is the device which requires tg3:

02:00.0 Ethernet controller: Broadcom Inc. and subsidiaries NetXtreme BCM57765 Gigabit Ethernet PCIe (rev 10)
Subsystem: Broadcom Inc. and subsidiaries NetXtreme BCM57765 Gigabit Ethernet PCIe
Kernel driver in use: tg3
Kernel modules: tg3

There does not appear to be a conflict, both devices function properly when the blacklist of tg3 is removed.
