Subject: net: sched: create tc_can_offload_extack() wrapper
Patch-mainline: v4.16-rc1
Git-commit: f9eda14f039294298643d034bc5c06340fe16cc0
References: bsc#1109837
Create a wrapper around tc_can_offload() that takes an additional
extack pointer argument in order to output an error message if TC
offload is disabled on the device.
In this way, the error message is handled by the core and can be the
same for all drivers.
