--- Comment #112 from Mahmoud Al-Qudsi <mqudsi@neosmart.net> ---
This bug has been open since 2012 and a workaround has been documented here=
 in
the comments since 2020. In the four years since, there have been no compla=
ints
of any regressions or other issues caused by using the vendor-patched versi=
on
of the driver or the ports net/realtek-re-kmod repackagement of it.

The latest version of the vendor-provided driver is 1.98.0 and is compatible
with FreeBSD 4 and up (per the source code), tested on FreeBSD 5.x and up (=
per
the readme in the driver tarball), and is officially supported on FreeBSD 7=
 and
up (per the product support website).

The vendor-patched version of the driver continues to be distributed under =
the
terms of the 3-clause BSD license.=20

re(4) says it is compatible with the 8139C+/8169/816xS/811xS/8168/810xE/8111
network cards, while the vendor-patched version of the driver says it is
compatible with
8169S/8169SB/8169SC/8168B/8168C/8168CP/8168D/8168DP/8168E/8168F/
8168FB/8168G/818GU/8168H/8168EP/8411/8168FP/
8101E/8102E/8103E/8401/8105E/8106E/8402/8125 so there is a difference in the
list of supported drivers though I do not know if this is a documentation
discrepancy or if support for the older 8139x, 811xS, and 8111 adapters has
actually been dropped (I would guess the former as otherwise it would be ra=
ndom
which cards have been dropped, assuming model numbers are linearly increasi=
ng
or at least linearly branching).=20

It seems to me that we should be able to update the in-kernel version of the
driver to use the patched 1.98.0 version that's been reported to be issue-f=
ree
so this can be fixed upstream. If support for those 3 models has in fact be=
en
dropped, we'd need to ship two separate versions of the re driver to keep
supporting the same chipsets, but I'm *guessing* that's not the case. Any
confirmation from users here who have used the net/realtek-re-kmod package =
with
8139x, 811xS, or 8111 network adapters would be very helpful.
