Revert "net: r8169: Disable multicast filter for RTL8168H and RTL8107E"
Browse files Browse the repository at this point in the history
commit 6a26310 upstream.

This reverts commit efa5f13.

I couldn't reproduce the reported issue. What I did, based on a pcap
packet log provided by the reporter:
- Used same chip version (RTL8168h)
- Set MAC address to the one used on the reporters system
- Replayed the EAPOL unicast packet that, according to the reporter,
  was filtered out by the mc filter.
The packet was properly received.

Therefore the root cause of the reported issue seems to be somewhere
else. Disabling mc filtering completely for the most common chip
version is a quite big hammer. Therefore revert the change and wait
for further analysis results from the reporter.
