Subject: [PATCH net 0/6][pull request] igc: Fix corner cases for TSN offload

Florian Kauer says:

The igc driver supports several different offloading capabilities
relevant in the TSN context. Recent patches in this area introduced
regressions for certain corner cases that are fixed in this series.

Each of the patches (except the first one) addresses a different
regression that can be separately reproduced. Still, they have
overlapping code changes so they should not be separately applied.

Especially #4 and #6 address the same observation,
but both need to be applied to avoid TX hang occurrences in
the scenario described in the patches.
