atm_qos struct should be the same both for user and kernel spaces. Via the __SO_ENCODE() macro it is used to define the SO_ATMQOS socket IOC. During the VRX518 support introduction, the atm_trafprm sturct nested into the atm_qos stucture was update with newer fields that are referenced by the ATM TC layer of the VRX518 TC driver. These new fields are intended to communicate information for extra traffic classes supported by the driver. But we are still using vanilla kernel headers to build the toolchain. Due to the atm.h header incoherency br2684ctl from linux-atm tools is incapable to configure the ATM bridge netdev: br2684ctl: Interface "dsl0" created sucessfully br2684ctl: Communicating over ATM 0.1.2, encapsulation: LLC br2684ctl: setsockopt SO_ATMQOS 22 <-- EINVAL errno br2684ctl: Fatal: failed to connect on socket; File descriptor in bad state There are two options to fix this incoherency. (a) update the header file in the toolchain to build linux-atm against updated atm_trafprm and atm_qos structures, or (b) revert atm_trafprm changes. Since there are no actual users of the extra ATM QoS traffic classes, just drop these extra traffic classes from vrx518_tc ATM TC layer and drop the kernel patch updating atm.h. Besides fixing the compatibility with linux-atm tools, removing the kernel patch should simplify kernel updates removing unneeded burden of maintenance. Run tested with FRITZ!Box 7530 with disabled extra traffic classes and then removed them entirely before the submission. CC: John Crispin <john@phrozen.org> Fixes: |
