--------------------------------
[ Upstream commit 6abc4ca5a28070945e0d68cb4160b309bfbf4b8b ]
the switch identifies itself as a BCM53012 (rev 5)... This patch has been tested & verified on OpenWrt's snapshot with Linux 5.10 (didn't test any older kernels). The MR32 is able to "talk to the network" as before with OpenWrt's SWITCHDEV b53 driver.
