Subject: [PATCH v3] net: r8169: Disable multicast filter for RTL8168H and RTL8107E
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@...gle.com>

Changes in v3:
- disable mc filter for VER_48
- update description
Changes in v2:
- add Fixes tag
- add net annotation
- update description
