Merge branch 'selftests-Various-fixes' 

Petr Machata says:

====================
selftests: Various fixes

This patch set contains various fixes whose common denominator is
improving quality of forwarding and mlxsw selftests.

Most of the fixes are improvements in determinism (such that timing and
latency don't impact the test performance). These were prompted by
regular runs of the test suite on a hardware emulator, the performance
of which is necessarily lower than that of the real device.

Patches #1 (from Ido), #2 and #3 make changes to ping limits.

Patches #4 and #5 add more sleep in places where things need more time
to finish.

Patches #6 and #7 fix two tests in the suite of mirror-to-gretap tests
where underlay involves a VLAN device over an 802.1q bridge.

Patches #8, #9 and #10 fix bugs in mirror-to-gretap test where underlay
involves a LAG device.

Patch #11 fixes a missed RET initialization in mirror-to-gretap flower
test.
