Remove 601-rt2x00-remove-mcu-requests-for-soc.patch as an equivalent patch is already included in upstream. Add 601-rt2x00-fix-hang-on-ifdown.patch which is not suitable for upstream inclusion but fixes a hang on ifdown under some circumstances and thus also fixes AP mode operation in OpenWRT.

Subject: [PATCH] rt2x00: fix rt2800pci hang on ifdown
|
|
|
|
rt2800pci hangs the system on rt305x SoC devices on ifdown. Work around
|
|
this issue by disabling TX DMA prior to restting the TX queue indices.
|
|
|
|
This patch is not suitable for upstream inclusion but is just meant as
|
|
a workaround until a proper solution is implemented.
