I'll split this patchset into two: - pass extack to drivers when doing tc offload (such as flower and others) and allow reporting of warnings in such cases. (according to a opt-in flag, as discussed in the other subthread) - allow more than one message The 1st may lead to the 2nd but right now it's more as a supposition, as there is no actual user for it yet.
