Starting from iputils s20190709 (used in Fedora 31), arping does not
support timeout being specified as a decimal:
$ arping -c 1 -I swp1 -b 192.0.2.66 -q -w 0.1
arping: invalid argument: '0.1'
Previously, such timeouts were rounded to an integer.
Fix this by specifying the timeout as an integer.

The variable is used by log_test() to check if the test case completely
successfully or not. In case it is not initialized at the start of a
test case, it is possible for the test case to fail despite not
encountering any errors.
Example:
```
...
TEST: Trap group statistics [ OK ]
TEST: Trap policer [FAIL]
Policer drop counter was not incremented
TEST: Trap policer binding [FAIL]
Policer drop counter was not incremented
```
Failure of trap_policer_test() caused trap_policer_bind_test() to fail
as well.
Fix by adding missing initialization of the variable.

Clean up after recent fixes, move address calculations
around and change the variable init, so that we can have
just one start_offset == end_offset check.
Make the check a little stricter to preserve the -EINVAL
error if requested start offset is larger than the region
itself.

Currently users have to choose a free snapshot id before
calling DEVLINK_CMD_REGION_NEW. This is potentially racy
and inconvenient.
Make the DEVLINK_ATTR_REGION_SNAPSHOT_ID optional and try
to allocate id automatically. Send a message back to the
caller with the snapshot info.
Example use:
$ devlink region new netdevsim/netdevsim1/dummy
netdevsim/netdevsim1/dummy: snapshot 1
$ id=$(devlink -j region new netdevsim/netdevsim1/dummy | \
jq '.[][][][]')
$ devlink region dump netdevsim/netdevsim1/dummy snapshot $id
[...]
$ devlink region del netdevsim/netdevsim1/dummy snapshot $id
v4:
- inline the notification code
v3:
- send the notification only once snapshot creation completed.
v2:
- don't wrap the line containing extack;
- add a few sentences to the docs.

Pull SPDX updates from Greg KH:
"Here are three SPDX patches for 5.7-rc1.
One fixes up the SPDX tag for a single driver, while the other two go
through the tree and add SPDX tags for all of the .gitignore files as
needed.
Nothing too complex, but you will get a merge conflict with your
current tree, that should be trivial to handle (one file modified by
two things, one file deleted.)
All three of these have been in linux-next for a while, with no
reported issues other than the merge conflict"
