+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Add support for legacy Broadcom FCS tags, which are similar to
+DSA_TAG_PROTO_BRCM_LEGACY.
+BCM5325 and BCM5365 switches require including the original FCS value and
+length, as opposed to BCM63xx switches.
+Adding the original FCS value and length to DSA_TAG_PROTO_BRCM_LEGACY would
+impact performance of BCM63xx switches, so it's better to create a new tag.

+Commit 46c5176c586c ("net: dsa: b53: support legacy tags") introduced support

+Subject: [PATCH] net: dsa: b53: add support for FDB operations on 5325/5365
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+BCM5325 and BCM5365 are part of a much older generation of switches which,
+due to their limited number of ports and VLAN entries (up to 256) allowed
+a single 64-bit register to hold a full ARL entry.
+This requires a little bit of massaging when reading, writing and
+converting ARL entries in both directions.
