Subject: Sets the BCDC priority to constant 0
X-Git-Tag: submit/tizen/20170801.050436~47
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=983cf7a23cc3f286f4c22d360387a5bac298d37c;p=platform%2Fkernel%2Flinux-rpi3.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.
