Linus Torvalds 64edfa6506 Delete some obsolete networking code
Old code like amateur radio and NFC have long been a burden
 to core networking developers. syzbot loves to find bugs
 in BKL-era code, and noobs try to fix them.
 
 If we want to have a fighting chance of surviving the LLM-pocalypse
 this code needs to find a dedicated owner or get deleted.
 We've talked about these deletions multiple times in the past
 and every time someone wanted the code to stay. It is never
 very clear to me how many of those people actually use the code
 vs are just nostalgic to see it go. Amateur radio did have
 occasional users (or so I think) but most users switched
 to user space implementations since its all super slow stuff.
 Nobody stepped up to maintain the kernel code.
 
 We were lucky enough to find someone who wants to help with NFC
 so we're giving that a chance. Let's try to put the rest of
 this code behind us.
