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.
