-Subject: [PATCH] sdk_dpaa: accept frames on RX even if larger than MTU
-
-Documentation/networking/netdevices.txt mentions that interfaces must
-be able to receive frames at least the size of the configured MTU. The
-behavior for received frames larger than the MTU is unspecified. We have
-been dropping these frames in software. Remove this behavior and accept
-them.
