Subject: [PATCH v2] net: r8169: Disable multicast filter for RTL_GIGA_MAC_VER_46

MAC_VER_46 ethernet adapters fail to detect eapol packets unless
allmulti is enabled. Add exception for VER_46 in the same way VER_35
has an exception.

Fixes: 6e1d0b898818 ("r8169:add support for RTL8168H and RTL8107E")
Signed-off-by: Patrick Thompson <ptf@...gle.com>

Changes in v2:
- add Fixes tag

- update description
