From: Marcel Holtmann Date: Thu, 7 Aug 2008 20:26:54 +0000 (+0200) Subject: [Bluetooth] Add parameters to control BNEP header compression X-Git-Tag: v2.6.27-rc3~69^2~2^2~2 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=28111eb2f5087c5aa5ec3697388f6c7d354b2ad8;p=linux-2.6 [Bluetooth] Add parameters to control BNEP header compression The Bluetooth qualification for PAN demands testing with BNEP header compression disabled. This is actually pretty stupid and the Linux implementation outsmarts the test system since it compresses whenever possible. So to pass qualification two need parameters have been added to control the compression of source and destination headers.
