Subject: realtek: switch to PSE driver for Plasma Cloud PSX28
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5b527dc7a4794455aa03b5fe231ca4afdee2813f;p=thirdparty%2Fopenwrt.git

realtek: switch to PSE driver for Plasma Cloud PSX28

Use the kernel PSE driver for PoE functionality on this device instead
relying on userspace apps. Drop the automatic selection for poemgr in
favor of the driver module.
