Subject: [PATCH] Revert "net: dsa: b53: Fix valid setting for MDB entries"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This reverts commit 1fae6eb0fc91d3ecb539e03f9e4dcd1c53ada553.
Upstream commit was a fix for an overlook of setting "ent.is_valid"
twice after 5d65b64a3d97 ("net: dsa: b53: Add support for MDB").
Since MDB support was not backported to stable kernels (it's not a bug
fix) there is nothing to fix there. Backporting this commit resulted in
"env.is_valid" not being set at all.

Subject: [PATCH] net: dsa: b53: Add support for MDB
In preparation for supporting IGMP snooping with or without the use of
a bridge, add support within b53_common.c to program the ARL entries for
multicast operations. The key difference is that a multicast ARL entry
is comprised of a bitmask of enabled ports, instead of a port number.

Subject: [PATCH] net: dsa: bcm_sf2: Add support for optional reset controller
line
Grab an optional and exclusive reset controller line for the switch and
manage it during probe/remove functions accordingly. For 7278 devices we
change bcm_sf2_sw_rst() to use the reset controller line since the
WATCHDOG_CTRL register does not reset the switch contrary to stated
documentation.

Subject: [PATCH] net: dsa: b53: Fix valid setting for MDB entries
When support for the MDB entries was added, the valid bit was correctly
changed to be assigned depending on the remaining port bitmask, that is,
if there were no more ports added to the entry's port bitmask, the entry
now becomes invalid. There was another assignment a few lines below that
would override this which would invalidate entries even when there were
still multiple ports left in the MDB entry.
Fixes: 5d65b64a3d97 ("net: dsa: b53: Add support for MDB")
