Allocate the skb for llc responses with the received packet size by using the size adjustable llc_frame_alloc. Don't allocate useless extra payload. Cleanup magic numbers. So, this fixes oops. Reported by Jim Westfall: kernel: skb_over_panic: text:c0541fc7 len:1000 put:997 head:c166ac00 data:c166ac2f tail:0xc166b017 end:0xc166ac80 dev:eth0 kernel: ------------[ cut here ]------------ kernel: kernel BUG at net/core/skbuff.c:95!
