Subject: [patch net-next 05/15] ixgbe: push cls_u32 and mqprio setup_tc processing into separate functions

From: Jiri Pirko <jiri@...lanox.com>

Let __ixgbe_setup_tc be a splitter for specific setup_tc types and push out
cls_u32 and mqprio specific codes into separate functions. Also change
the return values so they are the same as in the rest of the drivers.
