  • Device: Ubiquiti airGrid M5hp (FCC:SWX-M5G, SOC:AR9342 v2)
  • Software versions: trunk d.d. Dec 9 2020, OpenWrt SNAPSHOT, r15175+32-dd5b3b58d8
    /proc/cpuinfo shows
    AR9342 rev2, Ubiquiti nanostation M (XW), MIPS 74Kc V4.12

tried compiling for nanostation M XW and bullet M XW but same result. System boots, wireless works, but no ethernet at all.
in dmesg repeatedly:
ag71xx 19000000.eth: Could not connect to PHY device. Deferring probe.

It just does not find the lan at all.

Obviously without LAN the unit is useless.

can be closed. The issue is that this version of the airGrid M5hp has its single LAN port directly wired to the SOC 9342 and the Airgrid as such is not an option to choose from menuconfig.
Use firmware version:
openwrt-ath79-generic-ubnt_nanostation-loco-m-xw-squashfs-factory.bin

documented:
https://forum.archive.openwrt.org/viewtopic.php?id=60818

dmesg with working LAN:
libphy: Fixed MDIO Bus: probed
libphy: ag71xx_mdio: probed
ag71xx 19000000.eth: connected to PHY at mdio.0:01 [uid=004dd023, driver=Atheros 8032 ethernet]
eth0: Atheros AG71xx at 0xb9000000, irq 4, mode: mii

Thanks a lot. The above mentioned firmware worked properly on Airgrid m5 hp. It think it will be useful if the supported firmware on the openwrt page is also updated.
