Yeah, it's a good question ... We keep adding stuff here, so it'll be safer to alloc it. I get a fair number of stack size warnings on the build now (possibly due to the addition of the TPE fields?), and while they're probably fine for now (we get there from nl80211, so no deep stack), it's only going to increase - we have EHT patches already now, for example. johannes
