Subject: [RFC 0/3] net: imx: Provide support for L2 switch as switchdev accelerator

This patch series is a followup for the earlier effort [1]
to bring support for L2 switch IP block on some NXP devices.

This time it augment the fec driver, so the L2 switch is treated
as a HW network accelerator. This is minimal, yet functional
driver, which enables bridging between imx28 ENET-MAC ports.
