> Subject: [PATCH net v2 0/6] igc: Fix corner cases for TSN offload
> 
> 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.
