8f0229bef3 selftests: tc-testing: update ETS test 41f5 for clamped quanta
Commit "net/sched: ets: clamp quantum in parse and fallback paths"
moved the quantum floor into ets_quantum_parse(), so every explicitly
configured quantum is now clamped to [256, 1 << 20], not just the
psched_mtu() fallback.

Test 41f5 passes "quanta 4294967294 1 1" and matches the values back
verbatim, so all three bands now differ from what it expects:

  before: bands 3 quanta 4294967294 1 1
  after:  bands 3 quanta 1048576 256 256

Update the match pattern accordingly.

5754a1c9f9 tc-testing: add a test case for ETS offload
While reviewing the fix for unintentional u32 overflows in ets offload
code, Jamal said:

Extend tdc to allow setting hw-tc-offload via ethtool, and
add a test case to reproduce the division by zero fixed in [1].

d227cc0b1e selftests/tc-testing: update test definitions for local resources
With resources localized on a per test basis, some tests definitions
either contain redundant commands, were wrong or could be simplified.
Update all of them to match the new requirements.
