The resulting dependency seems quite logical to me: Some higher level networking functionality (iSCSI) depends on some lower level networking functionality (an actual driver). > You can't ignore these issues and just say "that's not the normal way > so I'm going to change it anyways." Admittedly I considered only my personal perspective. Now, to get the whole discussion productive again - where do we go from here? I don't think these drivers are so special that they really need to behave backwards to how (almost?) everything else is done... If changing it the way I did in the first try isn't deemed acceptable, would it be at least acceptable to remove those helper options (or, not as welcome from my perspective not the least because of the odd dependency on INET instead of NET, fold them into a single more generic one that others could also benefit from)? As to that INET vs NET dependency - is it possible that the network drivers really just need NET, but the iSCSI ones need INET? In which case the only common dependency would be PCI - certainly not worth a custom helper option.
