Subject: Sets the BCDC priority to constant 0
X-Git-Tag: archive/raspbian/4.9.51-1+rpi1~5^2~206
X-Git-Url: https://dgit.raspbian.org/?a=commitdiff_plain;h=89165ef64654c05d6466c60e71de7fce6c24b997;p=linux-4.9.git

Sets the BCDC priority to constant 0

This is to workaround for a possible issue in the
wireless chip firmware where some packets with
higher priorities seem to go missing.

See https://github.com/raspberrypi/linux/issues/1342 for
details.
