In manual mode a QP can be manually bound to a counter. If the counter
id(cntn) is not specified that kernel will allocate one. After a
successful bind, the cntn can be seen through "rdma statistic qp show".
And in unbind if lqpn is not specified then all QPs on this counter will
be unbound.
The manual and auto mode are mutual-exclusive.
Examples:
$ rdma statistic qp bind link mlx5_2/1 lqpn 178
$ rdma statistic qp bind link mlx5_2/1 lqpn 178 cntn 4
$ rdma statistic qp unbind link mlx5_2/1 cntn 4

With per-QP statistic counter support, a user is allowed to monitor
specific QPs categories, which are bound to/unbound from counters
dynamically allocated/deallocated.
In per-port "auto" mode, QPs are bound to counters automatically
according to common criteria. For example a per "type"(qp type)
scheme, where in each process all QPs have same qp type are bind
automatically to a single counter.
Currently only "type" (qp type) is supported. Examples:
$ rdma statistic qp set link mlx5_2/1 auto type on
$ rdma statistic qp set link mlx5_2/1 auto off

iproute has an utility function which checks if a string is a prefix for
another one, to allow use of abbreviated commands, e.g. 'addr' or 'a'
instead of 'address'.
This routine unfortunately considers an empty string as prefix
of any pattern, leading to undefined behaviour when an empty
argument is passed to ip:
# ip ''
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

parse_percent() currently allows to specify negative percentages
or value above 100%. However this does not seems to make sense,
as the function is used for probabilities or bandiwidth rates.
Moreover, using negative values leads to erroneous results
(using Bernoulli loss model as example):
$ ip link add test type dummy
$ ip link set test up
$ tc qdisc add dev test root netem loss gemodel -10% limit 10
$ tc qdisc show dev test
qdisc netem 800c: root refcnt 2 limit 10 loss gemodel p 90% r 10% 1-h 100% 1-k 0%
Using values above 100% we have instead:
$ ip link add test type dummy
$ ip link set test up
$ tc qdisc add dev test root netem loss gemodel 140% limit 10
$ tc qdisc show dev test
qdisc netem 800f: root refcnt 2 limit 10 loss gemodel p 40% r 60% 1-h 100% 1-k 0%
This commit changes parse_percent() with a check to ensure
percentage values stay between 1.0 and 0.0.
parse_percent_rate() function, which already employs a similar
check, is adjusted accordingly.
With this check in place, we have:
$ ip link add test type dummy
$ ip link set test up
$ tc qdisc add dev test root netem loss gemodel -10% limit 10
Illegal "loss gemodel p"
