selftests: mlxsw: tc_police_scale: Make test more robust
The test adds tc filters and checks how many of them were offloaded by
grepping for 'in_hw'.
iproute2 commit f4cd4f127047 ("tc: add skip_hw and skip_sw to control
action offload") added offload indication to tc actions, producing the
following output:
$ tc filter show dev swp2 ingress
...
filter protocol ipv6 pref 1000 flower chain 0 handle 0x7c0
eth_type ipv6
dst_ip 2001:db8:1::7bf
skip_sw
in_hw in_hw_count 1
action order 1: police 0x7c0 rate 10Mbit burst 100Kb mtu 2Kb action drop overhead 0b
ref 1 bind 1
not_in_hw
used_hw_stats immediate
The current grep expression matches on both 'in_hw' and 'not_in_hw',
resulting in incorrect results.
Fix that by using JSON output instead.

selftests: mlxsw: Reduce runtime of tc-police scale test
Currently, the test takes about 626 seconds to complete because of an
inefficient use of the device's TCAM. Reduce the runtime to 202 seconds
by inserting all the flower filters with the same preference and mask,
but with a different key.
In particular, this reduces the deletion of the qdisc (which triggers
the deletion of all the filters) from 66 seconds to 0.2 seconds. This
prevents various netlink requests from user space applications (e.g.,
systemd-networkd) from timing-out because RTNL is not held for too long
anymore.
