| |
2.6.27-stable review patch. If anyone has any objections, please let us know.
------------------ From: Oliver Hartkopp <oliver@hartkopp.net>
commit f706644d55f90e8306d87060168fef33804d6dd9 upstream.
Since commit d253eee20195b25e298bf162a6e72f14bf4803e5 the single CAN identifier filter lists handle only non-RTR CAN frames.
So we need to omit the check of these filter lists when receiving RTR CAN frames.
