 notes:
 - Tested against Enterprise SONiC Distribution by Dell Technologies.
 - Supports C(check_mode).
-- The SONiC buffer initialization command must be executed before attempting to apply
-- the configuration commands provided in this resource module. The buffer initialization will cause
-- the switch to reboot. See the "playbooks/common_examples/QoS_buffer_init.yaml" file
-- in this repo for an example playbook that initializes the buffers, waits for the reboot,
-- then proceeds with execution of QoS buffer configuration commands. Alternatively, make use of the
-- sonic_roce resource module to enable RoCEv2 default buffer configuration.
