Comment 9 Herbert Xu 2015-12-15 08:55:44 UTC

Subhendu, it looks like RHEL6 already has the MLD snooping support courtesy of https://bugzilla.redhat.com/show_bug.cgi?id=716263

Can you please verify that this fulfills your needs? Thanks!

Comment 10 Linda Wang 2016-08-25 13:54:49 UTC

See comment#9. The feature seems to be already in
RHEL6; therefore, close as CURRENTRELEASE.

Thanks!
