New Revision: 249074
URL: http://svnweb.freebsd.org/changeset/base/249074
Log:
Correct the multicast handling in the E1000 drivers as was
done in ixgbe, thanks to Mike Karels for this fix. When exiting
promiscuous mode MPE bit was being unconditionally cleared, this
should not be done if we are in MAX multicast groups.
