Default Use /sys/devices/lcs instead of /sys/devices/cu3088 (#561816).
The kernel change is in place and the cu3088 sysfs path is going away at
some point. For CTC and LCS devices, we need to use the
/sys/devices/lcs path.

Default Use /sys/devices/lcs instead of /sys/devices/cu3088 (#561816).
The commit to rhel6-branch should be synchronized with bug 561061 or
meanwhile rather 563548, but I guess you are aware of that.

cu3088 is replaced in some paths by either lcs OR ctcm depending on the
NETTYPE. IOW, it's not all lcs then.

Did you test this with lcs and ctcm?

FYI: I'll post a patch on top of this one dealing with slight changes in
sysfs for lcs and ctcm in set_device_online() determining the network
device name. Those changes are not related to the cu3088 conversion here.

That one is correct since this function is called for lcs only.

I misread the description then.


Did you test this with lcs and ctcm?


Nope. I only know how to use qeth. I have no idea what lcs is and I've only
used ctc on Hercules before.


FYI: I'll post a patch on top of this one dealing with slight changes in
sysfs for lcs and ctcm in set_device_online() determining the network
device name. Those changes are not related to the cu3088 conversion here.


I went ahead and pushed a patch to master to incorporate these changes, since
it really just looks like I got the description backwards and goofed up a
number of paths.
