-----------------------+-----------------------------------
Using BB r43770, when streaming large files with minidlna (about 15GB) on
Gbit lan (eth0 with r8169 driver), openwrt randomly (usually in the first
10 min.) drops the connection. The dlna client is a 100Mbit device. Also
there is an error in wireless device even though it's not involved in
stream. This is dmesg log of the error:
