Subject: [PATCH v3] net: r8169: Disable multicast filter for RTL8168H and RTL8107E
Date: Mon, 30 Oct 2023 16:50:14 -0400 [thread overview]
Message-ID: <20231030205031.177855-1-ptf@google.com> (raw)
RTL8168H and RTL8107E ethernet adapters erroneously filter unicast
eapol packets unless allmulti is enabled. These devices correspond to
RTL_GIGA_MAC_VER_46 and VER_48. Add an exception for VER_46 and VER_48
in the same way that VER_35 has an exception.
Fixes: 6e1d0b898818 ("r8169:add support for RTL8168H and RTL8107E")
Signed-off-by: Patrick Thompson <ptf@google.com>
---
Changes in v3:
- disable mc filter for VER_48
- update description
Changes in v2:
- add Fixes tag
- add net annotation
- update description
