Subject: [PATCH v2 net-next 0/4] Reduce coupling between DSA and Broadcom SYSTEMPORT driver

From: Vladimir Oltean <vladimir.oltean@....com>

Upon a quick inspection, it seems that there is some code in the generic
DSA layer that is somehow specific to the Broadcom SYSTEMPORT driver.
The challenge there is that the hardware integration is very tight between
the switch and the DSA master interface. However this does not mean that
the drivers must also be as integrated as the hardware is. We can avoid
creating a DSA notifier just for the Broadcom SYSTEMPORT, and we can
move some Broadcom-specific queue mapping helpers outside of the common
include/net/dsa.h.

Vladimir Oltean (4):
  net: dsa: move the Broadcom tag information in a separate header file
  net: dsa: export dsa_slave_dev_check
  net: systemport: use standard netdevice notifier to detect DSA
    presence
  net: dsa: remove the DSA specific notifiers
