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 Signed-off-by: Kiran Patil <kiran.patil@intel.com> Signed-off-by: Amritha Nambiar <amritha.nambiar@intel.com> Signed-off-by: Sudheer Mogilappagari <sudheer.mogilappagari@intel.com> Tested-by: Bharathi Sreenivas <bharathi.sreenivas@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>
