That's fine, I'll let you fight with the network people over that :) > igoeast:/sys/class/net/eth1# cd device/driver > > igoeast:/sys/class/net/eth1/device/driver# ls -l > total 0 > lrwxrwxrwx 1 root root 0 Dec 6 10:21 2 -> ../../../../devices/vio/2 > lrwxrwxrwx 1 root root 0 Dec 6 10:21 3 -> ../../../../devices/vio/3 > --w------- 1 root root 4096 Dec 6 10:21 bind > drwxr-xr-x 2 root root 0 Dec 6 10:21 cnx00 > drwxr-xr-x 2 root root 0 Dec 6 10:21 cnx02 > drwxr-xr-x 2 root root 0 Dec 6 10:21 cnx03 > drwxr-xr-x 2 root root 0 Dec 6 10:21 cnx04 > lrwxrwxrwx 1 root root 0 Dec 6 10:21 module -> > ../../../../module/iseries_veth > --w------- 1 root root 4096 Dec 6 10:21 uevent > --w------- 1 root root 4096 Dec 6 10:21 unbind > > The driver has a connection to all the other lpars, this is entirely > independent of the net devices. > > igoeast:/sys/class/net/eth1/device/driver# find cnx00/ > cnx00/ > cnx00/outstanding_tx > cnx00/remote_lp > cnx00/num_events > cnx00/reset_timeout > cnx00/last_contact > cnx00/state > cnx00/src_inst > cnx00/dst_inst > cnx00/num_pending_acks > cnx00/num_ack_events > cnx00/ack_timeout Hm, ok, it's odd as you are the only driver in the whole tree doing something like this, but it seems semi-resonable, so I can't complain :) I'll fix the core up to allow you to do this, thanks for the explanation. greg k-h _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
