Subject: [PATCH 0/3] net: bcmgenet: protect contended accesses

Some registers may be modified by parallel execution contexts and
require protections to prevent corruption.

A review of the driver revealed the need for these additional
protections.

  net: bcmgenet: synchronize EXT_RGMII_OOB_CTRL access
  net: bcmgenet: synchronize use of bcmgenet_set_rx_mode()
  net: bcmgenet: synchronize UMAC_CMD access
