+Subject: net: aquantia: Regression on reset with 1.x firmware
+
+On ASUS XG-C100C with 1.5.44 firmware a special mode called "dirty wake"
+is active. With this mode when motherboard gets powered (but no poweron
+happens yet), NIC automatically enables powersave link and watches
+for WOL packet.
+This normally allows to powerup the PC after AC power failures.
+
+Not all motherboards or bios settings gives power to PCI slots,
+so this mode is not enabled on all the hardware.
+
+4.16 linux driver introduced full hardware reset sequence
+This is required since before that we had no NIC hardware
+reset implemented and there were side effects of "not clean start".
+
+But this full reset is incompatible with "dirty wake" WOL feature
+it keeps the PHY link in a special mode forever. As a consequence,
+driver sees no link and no traffic.
+
+To fix this we forcibly change FW state to idle state before doing
+the full reset. This makes FW to restore link state.
