From 0699a73af3811b66b1ab5650575acee5eea841ab Mon Sep 17 00:00:00 2001 From: Clemens Ladisch Date: Mon, 22 Jul 2013 21:32:09 +0200 Subject: firewire: fix libdc1394/FlyCap2 iso event regression Commit 18d627113b83 (firewire: prevent dropping of completed iso packet header data) was intended to be an obvious bug fix, but libdc1394 and FlyCap2 depend on the old behaviour by ignoring all returned information and thus not noticing that not all packets have been received yet. The result was that the video frame buffers would be saved before they contained the correct data. Reintroduce the old behaviour for old clients.

So we rename the netlink API to NFC_CMD_FW_DOWNLOAD in order to avoid any terminology confusion from userspace.
