| |
Hi all!
As part of the VAMOS[0] research project at the University of Erlangen we're checking referential integrity between kernel KConfig options and in-code Conditional blocks.
In git commit [1] the option WLAN_80211 was removed as well as all references from within KConfig (as far as I can see) because the non 80211 drivers moved to staging.
I guess while doing so the help message was beliefed in which tells that this option only enables selection of certain drivers which is unfortunately wrong as this option is used in one header file[2] where it influences (as I'm reading it) the maximum size required for some networking header. Is this, as it seems, a bug in kernel code or rather harmless (intended?)?
Regards
Christoph Egger
