RDMA/hns: Support congestion control algorithm parameter configuration
hns RoCE supports 4 congestion control algorithms. Each algorihm
involves multiple parameters. Support configuring these parameters
by debugfs.
Here are some examples of this feature:
* The directory structure:
$ ls /sys/kernel/debug/hns_roce/0000\:35\:00.0/
dcqcn_cc_param dip_cc_param hc3_cc_param ldcp_cc_param
$ ls /sys/kernel/debug/hns_roce/0000\:35\:00.0/dcqcn_cc_param/
ai al alp ashift cnp_time f g lifespan max_speed tkp tmp
* Read the value of a param:
$ cat /sys/kernel/debug/hns_roce/0000\:35\:00.0/dcqcn_cc_param/ai
1
* Set a new value for a param:
$ echo 2 > /sys/kernel/debug/hns_roce/0000\:35\:00.0/dcqcn_cc_param/ai
