--- Comment #113 from Richard Russo <freebsd@ruka.org> ---
(In reply to Mahmoud Al-Qudsi from comment #112)

> In the four years since, there have been no complaints of any regressions=
 or other issues caused by using the vendor-patched version of the driver o=
r the ports net/realtek-re-kmod repackagement of it.

As I reported above, the vendor driver emits ethernet pause frames, which is
undesirable on my network; and it's not configurable. Of course, being unab=
le
to send or receive frames is worse; but the opaque nature of the vendor dri=
ver
makes it hard to do any refinement.

When I saw the vendor driver is opaque, look at the function re_enable_EEE
(line 8087). That's a whole lot of probably important hardware configuration
that we have no idea what's going on for.

That said, perhaps the watchdog message could be adjusted to refer to this =
bug
or the realtek-re-kmod port. Or maybe the vendor could be persuaded to rele=
ase
more details about their hardware?
