Subject: [PATCH] Revert "net: dsa: bcm_sf2: Also configure Port 5 for 2Gb/sec
on 7278"
This reverts commit 7458bd540fa0a90220b9e8c349d910d9dde9caf8 ("net: dsa:
bcm_sf2: Also configure Port 5 for 2Gb/sec on 7278") as it causes
advanced congestion buffering issues with 7278 switch devices when using
their internal Giabit PHY. While this is being debugged, continue with
conservative defaults that work and do not cause packet loss.

VLAN entries yet, since that happens later when interfaces get brought
up. When b53_configure_vlan() is called again from suspend/resume we
need to restore all VLAN entries though.

On 7278, port 7 of the switch connects to the ASP UniMAC which is not
capable of processing VLAN tagged frames. We can still allow the port to
be part of a VLAN entry, and we may want it to be untagged on egress on
that VLAN because of that limitation.

Subject: [PATCH] net: dsa: b53: Deny enslaving port 7 for 7278 into a bridge
On 7278, port 7 connects to the ASP which should only receive frames
through the use of CFP rules, it is not desirable to have it be part of
a bridge at all since that would make it pick up unwanted traffic that
it may not even be able to filter or sustain.

Subject: [PATCH] net: dsa: bcm_sf2: Disable learning for ASP port
We don't want to enable learning for the ASP port since it only receives
directed traffic, this allows us to bypass ARL-driven forwarding rules
which could conflict with Broadcom tags and/or CFP forwarding.

Subject: [PATCH] net: dsa: bcm_sf2: Check earlier for FLOW_EXT and
FLOW_MAC_EXT
We do not currently support matching on FLOW_EXT or FLOW_MAC_EXT, but we
were not checking for those bits being set in the flow specification.
The check for FLOW_EXT and FLOW_MAC_EXT are separated out because a
subsequent commit will add support for matching VLAN TCI which are
covered by FLOW_EXT.

Subject: [PATCH] net: dsa: bcm_sf2: Support specifying VLAN tag egress rule
The port to which the ASP is connected on 7278 is not capable of
processing VLAN tags as part of the Ethernet frame, so allow an user to
configure the egress VLAN policy they want to see applied by purposing
the h_ext.data[1] field. Bit 0 is used to indicate that 0=tagged,
1=untagged.
