Summary: This switch is based off of the AR8327/AR8337 external switch/PHY. However unlike the AR8327/AR8337 it itself doesn't have any PHYs; instead an external PHY connects to it using the PSGMII port. Differential Revision: https://reviews.freebsd.org/D34112 Reviewed by: manu This code is inspired by the ar40xx code in openwrt, which itself is based on the Qualcomm QCA-SSDK. Both of these sources are, amusingly, BSD licenced - and thus I have included some of the comments in the hardware workaround paths to document some of the magic numbers.
