-Subject: [PATCH] ipv6/addrconf: call ipv6_mc_up() for non-Ethernet interface
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Rafał found an issue that for non-Ethernet interface, if we down and up
-frequently, the memory will be consumed slowly.
-
-The reason is we add allnodes/allrouters addressed in multicast list in
-ipv6_add_dev(). When link down, we call ipv6_mc_down(), store all multicast
-addresses via mld_add_delrec(). But when link up, we don't call ipv6_mc_up()
-for non-Ethernet interface to remove the addresses. This makes idev->mc_tomb
-getting bigger and bigger. The call stack looks like:
-
-addrconf_notify(NETDEV_REGISTER)
- ipv6_add_dev
- ipv6_dev_mc_inc(ff01::1)
- ipv6_dev_mc_inc(ff02::1)
- ipv6_dev_mc_inc(ff02::2)
-
-addrconf_notify(NETDEV_UP)
- addrconf_dev_config
- /* Alas, we support only Ethernet autoconfiguration. */
- return;
-
-addrconf_notify(NETDEV_DOWN)
- addrconf_ifdown
- ipv6_mc_down
- igmp6_group_dropped(ff02::2)
- mld_add_delrec(ff02::2)
- igmp6_group_dropped(ff02::1)
- igmp6_group_dropped(ff01::1)
-
-After investigating, I can't found a rule to disable multicast on
-non-Ethernet interface. In RFC2460, the link could be Ethernet, PPP, ATM,
-tunnels, etc. In IPv4, it doesn't check the dev type when calls ip_mc_up()
-in inetdev_event(). Even for IPv6, we don't check the dev type and call
-ipv6_add_dev(), ipv6_dev_mc_inc() after register device.
-
-So I think it's OK to fix this memory consumer by calling ipv6_mc_up() for
-non-Ethernet interface.
-
-v2: Also check IFF_MULTICAST flag to make sure the interface supports
- multicast

-Subject: [PATCH] net: thunderx: workaround BGX TX Underflow issue
-
-While it is not yet understood why a TX underflow can easily occur
-for SGMII interfaces resulting in a TX wedge. It has been found that
-disabling/re-enabling the LMAC resolves the issue.
