From: Stefan Richter Date: Sun, 18 Jul 2010 11:00:50 +0000 (+0200) Subject: firewire: cdev: add PHY pinging X-Git-Tag: v2.6.36-rc1~490^2^3~8 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cc550216ae9a2993ef3973464714dc1a39ab1f86;p=pandora-kernel.git firewire: cdev: add PHY pinging This extends the FW_CDEV_IOC_SEND_PHY_PACKET ioctl() for /dev/fw* to be useful for ping time measurements. One application for it would be gap count optimization in userspace that is based on ping times rather than hop count. (The latter is implemented in firewire-core itself but is not applicable to beta PHYs that act as repeater.) Signed-off-by: Stefan Richter --- Reading git-diff-tree failed
