Ping.

Until now, two types of files are supported:
Files with flags==0 and files with flags&0x02.
The specification requires that (flags&0x02)
implies flags==2 or possibly flags==6: "if bit
9 is 1, bits 11 and 12 must be 0"

After my patch, the following values are
accepted for flags: 0, 2, 4, 6

Which value is problematic?
