Add an offload support for RED qdisc for mlxsw driver. The first patch adds the ability to offload RED qdisc by using ndo_setup_tc. It gives RED three commands, to offload, change or delete the qdisc, to get the qdisc generic stats and to get it's RED xstats. There is no enforcement on a driver to offload or not offload the qdisc and it is up to the driver to decide. RED qdisc is first being created and only later graft to a parent (unless it is a root qdisc). For that reason the return value of the offload replace command that is called in the init process doesn't reflect actual offload state. The offload state is determined in the dump function so it can be reflected to the user. This function is also responsible for stats update. The patchses 2-3 change the name of TC_SETUP_MQPRIO & TC_SETUP_CBS to match with the new convention of QDISC prefix. The rest of the patchset is driver support for the qdisc. Currently only as root qdisc that is being set on the default traffic class. It supports only the following parameters of RED: min, max, probability and ECN mode. Limit and burst size related params are being ignored at this moment.
