Subject: [PATCH] net: ipqess: add dual-GMAC support for TEW-829DRU
The TRENDnet TEW-829DRU has two switches connected to the IPQ4019 ESS:
- GMAC0 -> QCA8075 (5-port switch, ports 0-4)
- GMAC1 -> QCA8337 (7-port switch, port 5 in RRD)
Both GMACs share the single EDMA hardware block. This patch adds an
optional second net_device (netdev2) that is created when the DT node
contains the property "qcom,gmac1-port". Incoming packets are demuxed
in ipqess_rx_poll() using the RRD port-id field; outgoing packets from
either netdev share the same TX rings.
The second interface's MAC address is read from a DT node referenced by
"qcom,gmac1-netdev", or derived automatically from the primary MAC by
eth_hw_addr_gen() if that phandle is absent.
