There's a known-working driver in the kernel source tree for this device already. Start by looking at what data it's placed in the skb when it calls that routine, and how it differs from what you filled in. For bonus points - lose the 'unsigned char t[]' array and replace it with a bunch of explicit 'skb->foo = bar' statements. In particular, that assures that you haven't missed a 0x15 27 bytes into the array, or failed to allow alignment padding bytes.
