+Date: Wed, 27 Jul 2016 11:33:14 +0300
+Subject: [PATCH] stmmac: Disable frame filtering completely
+
+For some [still unknown] reason in ARC SDP boards
+DW GMAC doesn't enter promiscuous mode if eth0 gets
+added to the br-lan interface before Ethernet PHY finishes
+autonegotiation (PHY gets reset on DW GMAC start).
+
+As a work-around we completely disable frame filtering
+in GMAC hardware which gives us working bridge that consists
+of eth0 and wlan0 (USB Wi-Fi dongle). I.e. we finally have
+working "Dumb AP" setup made of ARC AXS10x boards.
