Add support in driver for TC_QDISC_SETUP_MQPRIO. This support
enables instantiation of channels in HW using existing MQPRIO
infrastructure which is extended to be offloadable. This
provides a mechanism to configure dedicated set of queues for
each TC.
Configuring channels using "tc mqprio":
--------------------------------------
tc qdisc add dev <ethX> root mqprio num_tc 3 map 0 1 2 \
queues 4@0 4@4 4@8 hw 1 mode channel
Above command configures 3 TCs having 4 queues each. "hw 1 mode channel"
implies offload of channel configuration to HW. When driver processes
configuration received via "ndo_setup_tc: QDISC_SETUP_MQPRIO", each
TC maps to HW VSI with specified queues.
User can optionally specify bandwidth min and max rate limit per TC
(see example below). If shaper params like min and/or max bandwidth
rate limit are specified, driver configures VSI specific rate limiter
in HW.
Configuring channels and bandwidth shaper parameters using "tc mqprio":
----------------------------------------------------------------
tc qdisc add dev <ethX> root mqprio \
num_tc 4 map 0 1 2 3 queues 4@0 4@4 4@8 4@12 hw 1 mode channel \
shaper bw_rlimit min_rate 1Gbit 2Gbit 3Gbit 4Gbit \
max_rate 4Gbit 5Gbit 6Gbit 7Gbit
Command to view configured TCs:
-----------------------------
tc qdisc show dev <ethX>
Deleting TCs:
------------
tc qdisc del dev <ethX> root mqprio
