Move brcm_leg_tag_rcv() definition to top.
This function is going to be shared between two different tags.

Subject: [PATCH] net: dsa: tag_brcm: add support for legacy FCS tags
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
for legacy tags, but it turns out that BCM5325 and BCM5365 switches require
the original FCS value and length, so they have to be treated differently.

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.

for BCM5325
MIME-Version: 1.0

CPU port should be B53_CPU_PORT instead of B53_CPU_PORT_25 for
B53_PVLAN_PORT_MASK register.

Subject: [RFC PATCH net-next v2 10/10] net: dsa: b53: ensure BCM5325 PHYs are
enabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
According to the datasheet, BCM5325 uses B53_PD_MODE_CTRL_25 register to
disable clocking to individual PHYs.
Only ports 1-4 can be enabled or disabled and the datasheet is explicit
about not toggling BIT(0) since it disables the PLL power and the switch.
